A bearing capacity failure is defined as a foundation failure that occurs when the shear stresses in the soil exceed the shear strength of the soil. Bearing capacity failures of foundations can be grouped into three categories，as follows :G eneral shear. As shown in Figure 12. 1，a general shear failure involves total rupture of the underlying soil. There is a continuous shear failure of the soil ( solid lines) from belowthe footing to the ground surface. When the load is plotted versus settlement of the footing，there is a distinct load at which the foundation fails ( solid circle) ，and this is designated Qult. The value of Qultdivided by the width B and length L of the footing is considered to be the ultimate bearing capacity qultof the footing. The ultimate bearing capacity has been defined as the bearing stress that causes a sudden catastrophic failure of the foundation.Figure 12. 1 General shear foundation failureNote in Figure 12. 1 that a general shear failure ruptures and pushes up the soil on both sides of the footing. For actual failures in the field，the soil is often pushed up on only one side of the footing，with subsequent tilting of the structure. A general shear failure occurs for soils that are in a dense or hard state.Punching shear. As shown in Figure 12. 2，a punching shear failure does not develop the distinct shear surfaces associated with a general shear failure. For punching shear，the soil outside the loaded area remains relatively uninvolved and there is minimal movement of soil on both sides of the footing.Figure 12. 2 Punching shear foundation failureThe process of deformation of the footing involves compression of soil directly belowthe footing as well as the vertical shearing of soil around the footing perimeter. As shown in Figure 12. 2，the load settlement curve does not have a dramatic break and for punching shear，the bearing capacity is often defined as the first major nonlinearity in the load-settlement curve( open circle) . A punching shear failure occurs for soils that are in a loose or soft state.Local shear failure. As shown in Figure 12. 3，local shear failure involves rupture of the soil only immediately belowthe footing. There is soil bulging on both sides of the footing，but the bulging is not as significant as in general shear. Local shear failure can be considered as a transitional phase between general shear and punching shear. Because of the transitional nature of local shear failure，the bearing capacity could be defined as the first major nonlinearity in the load-settlement curve ( open circle) or at the point where the settlement rapidly increases ( solid circle) . A local shear failure occurs for soils that have a medium density or are in a firm state.Figure 12. 3 Local shear foundation failureCompared to the number of structures damaged by settlement，there are far fewer structures that have bearing capacity failures. This is because of the following factors:Settlement governs. The foundation design is based on several requirements，and two of the main considerations are: ① settlement due to the building loads must not exceed tolerable values and ② there must be an adequate factor of safety against a bearing capacity failure. In most cases，settlement governs，and the foundation bearing pressures recommended by the geotechnical engineers are based on limiting the amount of settlement.Extensive studies. Extensive studies of bearing capacity failures have led to the development of bearing capacity equations that are routinely used in practice to determine the ultimate bearing capacity of the foundation.Factor of safety. In order to determine the allowable bearing pressure qall，the ultimate bearing capacity qultis divided by a factor of safety. The normal factor of safety used for bearing capacity analyses is 3. This is a high factor of safety compared to other factors of safety，such as only 1. 5 for slope stability analyses.Minimum footing sizes. Building codes often require minimum footing sizes and embedment depths.Allowable bearing pressures. In addition，building codes often have maximum allowable bearing pressures for different soil and rock conditions. Table 12. 1 presents maximum allowable bearing pressures based on the Uniform Building Code. Especially in the case of dense or stiff soils，these allowable bearing pressures often have adequate factors of safety.Table 12. 1 Allowable bearing pressures① Minimum footing width and embedment depth equals 1 ft ( 0. 3 m) .② An increase of 20% of the allowable bearing pressure is allowed for each additional foot ( 0. 3 m) of width or depth up to the maximum allowable bearing pressures listed in column 3. An exception is plastic soil.Footing dimensions. Usually the structural engineer will determine the size of the footings by dividing the maximum footing load ( dead load plus live load) by the allowable bearing pressure. Typically the structural engineer uses values of dead and live loads that also contain factors of safety. For example，the live load may be from the local building code which specifies minimum live load requirements for specific building uses. Such building code values often contain a factor of safety，which is in addition to the factor of safety of 3 that was used to determine the allowable bearing pressure.Because the bearing capacity failure involves a shear failure of the underlying soil，the analysis will naturally include the shear strength of the soil. As indicated in Figure 12. 1 to 12. 3，the depth of the bearing capacity failure is rather shallow. It is often assumed that the soil involved in the bearing capacity failure can extend to a depth equal to B ( footing width) belowthe bottom of the footing. Thus for bearing capacity analysis，this zone of soil should be evaluated for its shear strength properties.The documented cases of bearing capacity failures indicate that usually the following three factors ( separately or in combination ) are the cause of the failure: ① there was an overestimation of the shear strength of the underlying soil，② the actual structural load at the time of the bearing capacity failure was greater than that assumed during the design phase，or ③ the site was subjected to alteration，such as the construction of an adjacent excavation，which resulted in a reduction in support and a bearing capacity failure.A famous case of a bearing capacity failure is the Transcona grain elevator，located at Transcona，near Winnipeg，Canada. At the time of failure，the grain elevator was essentially fully loaded. The foundation had been constructed on clay which was described as a stiff clay.As indicated in Table 12. 2 ， common types of shallowfoundation include spread footings for isolated columns，combined footings for supporting the load from more than one structural unit，strip footings for walls，and mats or raft foundations constructed at or near ground surface. Shallowfootings often have an embedment that is less than the footing width.Table 12. 2 Bearing capacity factors ( Nc，Nrand Nq) that automatically incorporate allowances for local shear and punching shear failureNote: At high friction angles，bearing capacity factors increase rapidly，and these values should be used with caution.Bearing capacity equation. The most commonly used bearing capacity equation is that equation developed by Terzaghi. For a uniform vertical loading of a strip footing，Terzaghi ( 1943) assumed a general shear failure ( Figure 12. 1) in order to develop the following bearing capacity equation:勘查工程专业英语 where qultis ultimate bearing capacity for a strip footing ( kPa or psf ) ; Qultis vertical load causing a general shear failure of the underlying soil ( Figure 12. 1) ; B is width of the strip footing ( m or ft) ; L is length of the strip footing ( m or ft) ; γtis total unit weight of the soil ( kN /m3) ; Dfis vertical distance from the ground surface to the bottom of the strip footing ( m or ft) ; c is cohesion of the soil underlying the strip footing ( kPa or psf ) ; Nc，Nr，Nqare dimensionless bearing capacity factors respectively.As indicated in Equation ( 12. 1) ，there are three terms that are added together to obtain the ultimate bearing capacity of the strip footing. These terms represent the following:·cNc: The first term accounts for the cohesive shear strength of the soil located belowthe strip footing. If the soil belowthe footing is cohesionless ( i. e. ，c = 0) ，then this term is zero.: The second term accounts for the frictional shear strength of the soil located belowthe strip footing. The friction angle Φ is not included in this term，but is accounted for by the bearing capacity factor Nγ. Note that γtrepresents the total unit weight of the soil located belowthe footing.·γtDfNq: This third term accounts for the soil located above the bottom of the footing. The value of γttimes Dfrepresents a surcharge pressure that helps to increase the bearing capacity of the footing. If the footing was constructed at ground surface ( i. e. ，D =0) ，then this term would equal zero. This third term indicates that the deeper the footing，the greater the ultimate bearing capacity of the footing. In this term，γtrepresents the total unit weight of the soil located above the bottom of the footing. The total unit weight above and belowthe footing bottom may be different，in which case different values are used in the second and third terms of Equation ( 12. 1) .In order to calculate the allowable bearing pressure qall，which is used to determine the size of the footings，the following equation is used:勘查工程专业英语where qallis allowable bearing pressure ( kPa or psf ) ; qultis ultimate bearing capacity from Equation ( 12. 1) ; F is factor of safety. For bearing capacity analysis，the commonly used factor of safety is equal to 3. Building codes often list allowable bearing pressures versus soil or rock types. Table 12. 1，for example，presents the allowable bearing pressures qallfrom the Uniform Building Code ( 1997) .Bearing capacity factors. Table 12. 2 presents bearing capacity factors Nc，Nrand Nq. There are many other charts，graphs，and figures that present bearing capacity factors developed by other engineers and researchers based on varying assumptions. Some of these bearing capacity factors are even listed to an accuracy of five significant figures. These bearing capacity factors imply an accuracy which simply does not exist because the bearing capacity equation is only an approximation of the actual bearing failure. In Table 12. 2，up to two significant figures are provided for the dimensionless bearing capacity factors. As indicated in Table 12. 2，the bearing capacity factors are directly related to the friction angle Φ of the soil. A dense cohesionless soil would tend to have a high friction angle and high bearing capacity factors，resulting in a large ultimate bearing capacity. On the other hand，a loose cohesionless soil would tend to have a lower friction angle and lower ultimate bearing capacity. Thus a major disadvantage of building code values ( such as those in Table 12. 1) is that they consider only the material type，and not the density condition of the soil which influences the friction angle Φ and bearing capacity factors. Building code values tend to underestimate the allowable bearing pressure for dense cohesionless soil，but may overestimate the allowable bearing pressure for loose cohesionless soil.Note in Table 12. 2 that the bearing capacity factors rapidly increase at high friction anglesΦ. These bearing capacity factors should be used with caution，because natural soils are not homogeneous and the natural variability of such soil will result in weaker layers that will be exploited during a bearing capacity failure.Terzaghi originally developed the bearing capacity equation ( Equation ( 12. 1 ) ) for a general shear bearing capacity failure. This type of bearing capacity failure is shown in Figure12. 1 and will develop for dense or stiff soil. For loose or soft soil，there will be a punching shear failure as shown in Figure 12. 2. The bearing capacity factors presented in Table 12. 2 have been empirically adjusted and automatically incorporate allowances for local shear and punching shear.Spread and combined footings. Equation ( 12. 1 ) was developed by Terzaghi for strip footings. For other types of footings and loading conditions，corrections need to be applied to the bearing capacity equation. Many different types of corrections have been proposed. One commonly used form of the bearing capacity equation for spread ( square footings ) and combined footings ( rectangular footings) subjected to uniform vertical loading，is as follows:勘查工程专业英语Equation ( 12. 3 ) is similar to Equation ( 12. 1 ) and the terms have the same definitions. An important consideration is that，for the strip footing，the shear strength is actually based on a plane strain condition ( soil is confined along the long axis of the footing) . It has been stated that the friction angle Φ is about 10 percent higher in the plane strain condition than the friction angle Φ measured in the triaxial apparatus indicate that the friction angle Φ in plane strain is larger than Φ in triaxial shear by 4° to 9° for dense sands. A difference in friction angle of 4° to 9° has a significant impact on the bearing capacity factors ( see Table12. 2) . In practice，plane strain shear strength tests are not performed and thus
