三峡大坝

简单原理:把水的势能转化成电能,大坝蓄水以抬高水位,水位高势能就大,然后高势能水冲击涡轮使涡轮旋转从而带动发电机工作.涡轮就像我们小时候玩的风车,只是它比风车效率高

发电原理就是通过水流产生压力，浙江压力提供给大坝内的一些设置，这时候就可以通过这些设置来实现发电，也就是所谓的将水源的位能转化为动能，再将动能转化为电能的一种方式。

三峡高度差使水流具有能量，带动涡轮机发电。都是运用了能量的相互转换。利用水的重力势能转化为发电机的动能.最终转化为电能 ，

①火车对路基压力很大，据p=FS知，为减小火车对地基的压强，必须增大受力面积，把钢轨铺在枕木上，可以增大火车与路基的受力面积，从而减小火车对路基的压强，防止压陷路基，火车通过时能安全行驶．②因为水的压强随深度增加而增大，故为了防止大坝被水压冲毁，拦河大坝所以修成“上窄下宽”的形状；③三峡大坝的船闸由上下两个阀门组成一个闸室，当上游阀门打开时，闸室与上游通过阀门组成连通器，使闸室内的水位与上游水位相平；故船闸的原理即为连通器的原理，即三峡大坝的船闸是连通器在实际中的具体应用；故答案为：①增大受力面积；减小压强；②液体内部压强随深度的增加而增大；③连通器．

很简单，根据U型连通器的原来，初中物理书上有的

（1）大坝底部做得比较宽，一方面是增大了大坝与坝基的接触面积，减小了对坝基的压强；另一方面是因为水的压强随深度的增加而增大，大坝底部所受的水压较大，所以大坝底部做得比较宽，可以抗击底部较大的水压，以保证大坝的安全． （2）水对坝底的压强为p=ρgh=1.0×10 3 kg/m 3 ×10N/kg×20m=2×10 5 Pa 据船闸的结构特点可知，其在工作时，上端开口，下部连同，即符合连通器的定义，所以船闸是利用连通器的原理工作的． 故答案为：一方面是增大了大坝与坝基的接触面积，减小了对坝基的压强；另一方面因为是因为水的压强随深度的增加而增大，大坝底部所受的水压较大，所以大坝底部做得比较宽，可以抗击底部较大的水压，以保证大坝的安全；2×10 5 ；连通器．

这样能让大型船只通过。

水面下100m深处水的压强：p=ρgh=1.0×103kg/m3×9.8N/kg×100m=9.8×105Pa；人们根据连通器的原理修建了三峡大坝船闸，三峡大坝的船闸是世界上最大的连通器；水位每下降1m，水对坝底减小的压强：△p=ρg△h=1.0×103kg/m3×9.8N/kg×1m=9.8×103Pa；水对坝底减小的压力：△F=△pS=9.8×103Pa×1m2=9.8×103N．故答案为：9.8×105；连通器；9.8×103．

（1）三峡大坝的船闸由上下两个阀门组成一个闸室，当上游阀门打开时，闸室与上游通过阀门组成连通器，使闸室内的水位与上游水位相平；故船闸的原理即为连通器的原理，即三峡大坝的船闸是连通器在实际中的具体应用； （2）轮船是采用空心的办法增大可以利用的浮力； 故答案为：连通器；空心．

1.游船过三峡大坝船闸船闸工作原理！船闸是一种克服河道上因筑坝(或天然)而产生的集中水位差的过船建筑物。它由上、下闸首、闸门和闸室组成。闸门充水放水使水位升降，像一个特殊的水梯，但它没有不要像普通电梯和升船机那样靠电力升降。船闸的闸首和闸室都是固定的水工建筑物。闸首、闸门和闸室形成固定的闸室，起到挡水的作用。当船舶通过船闸时，由廊道和阀门组成的输水系统充满闸室，闸室内水位上升；水从闸室泄漏，闸室内的水位下降。船舶在闸室内依靠水的浮力，随闸室内水位升降，与上游或下游水面平齐，以克服水位差。它通常被称为跨坝建筑。由于过闸船舶是靠水的浮力托起的，运行费用相对较低，是过闸建筑物的一种主要型式。船闸是如何工作的？让让我们来看看三峡船闸的工作原理。(1)当船舶需要从上游向下游通过船闸时，船闸打开通向上游的进水阀，使船闸内水位上升到与上游相同的水位。当船舶进入闸门时，关闭通向上游的进水阀和通向上游的闸门，打开通向下游的出水阀，将闸门内多余的水排出，使船闸内水位与下游水位相等，然后打开通向下游的闸门出闸。(2)当船舶需要从下游向上游通过船闸时，船闸打开通向下游的出水阀，当船闸内水位降至下游水位时，船舶进入闸门，然后关闭通向下游的出水阀和通向下游的闸门，打开通向上游的进水阀，使船闸内水位升至上游水位，再打开通向上游的闸门出闸。三峡船闸工作原理三峡船闸的工作原理是连通原理。三峡有五座船闸。当船到达最低的船闸时，船闸的入口将关闭，然后开始注水。当水位上升到一定高度时，(与第二个船闸的高度齐平)。船舶进入二级船闸，再次开始注水，以此类推，到达五级船闸，最后到达上游，利用水的浮力和连通性原理。船闸是如何工作的？让让我们来看看三峡船闸的工作原理。船闸是利用箱形闸室的水位变化来升船的航道工程建筑物。它是一种通航建筑物，用于克服航道中的集中水位下降，将船舶从一个水位段提升或下降到另一个水位段。船闸修建在内河航道的水利枢纽，有时需要修建船闸来控制河口或港池以外的潮差。2.游船过三峡大坝船闸需用时间按照我们的设计，从上游引航道到下游引航道，船舶通过三峡船闸一次需要3个多小时，上上下下也需要同样的时间。三峡双线五级船闸是一座单行道。原则上，它从北面的水闸下去，从南面的水闸上去。如果北面的船闸坏了，南面的船闸也是一个方向运行，每4到6个小时换一次方向。如果过往船只较多，通过船闸的时间一般相隔1小时左右。如果船只较少，就要等到一定数量的船只经过，视具体情况而定。3.三峡大坝的船闸三峡大坝开坝时间取决于一次能开多少船，船走远了就关。一般节假日开放时间多。不规则提升。当前位置三峡大坝蓄水位高于海平面175米，世界上最大的河流是长江4.在三峡大坝船舶是如何过闸的比如以下游船只进入上游。当货船进入船闸时，船闸的闸门会关闭，从而形成一个相对封闭的空间。这时候会往船闸里注水，让水面不断上升，船自然也随之上升。当达到一定高度后，船就可以进入下一级船闸，从而一级一级地爬上楼梯。三峡大坝的船闸空间如此之大，即使是两艘大船也可以并排等待通过。因为长江上所有的船只都要靠船闸通过，三峡大坝的船闸成了世界上最繁忙的水道。5.游船过三峡大坝船闸图片齿轮齿条爬升式三峡升船机是一种齿轮齿条爬升式垂直升船机，由上游引航道、上闸首、船厢、下闸首和下游引航道组成。设计的主承力舱长132米，宽23.4米，高10米，带水总提升重量约15500吨。该升船机过船规模3000吨，年单向通过能力350万吨，最大垂直提升高度113米，上游通航水位变幅30米，下游通航水位变幅11.8米。是世界上规模最大、技术难度最高的升船机工程。三峡工程永久通航设施由双线五级船闸和升船机组成，全部布置在长江左岸。经过六年的建设，永久船闸已经建成通航。目前，船舶通过船闸的时间约为三小时。但由于设计方案的反复讨论论证，升船机于2007年底进入前期施工准备。2015年3月建成后，船舶通过升船机过坝的时间仅为40分钟左右。据了解，三峡升船机基础开挖和边坡支护工程已经完成。葛洲坝集团负责人表示，将精心组织主体工程建设，打造又一个世界级精品工程。6.三峡大坝开闸过船三峡普通游船门票每人560-950不等。一般邮轮分为一等、二等、三等。三峡豪华邮轮的房间分为标准间、阳台间、豪华套房、总统套房，所以邮轮船票是每人1100到5000。根据您选择的所有房间类型，会有一些差异。三峡豪华游轮相当于五星级标准，游轮设施豪华，餐食豪华。7.三峡大坝游船过闸的船票客船如何通过三峡大坝：简单来说，船闸就是连接大坝上下游水位差的介质。也就是利用连接器原理改变船闸内水位的装置。利用该装置，船舶可以顺利通过船闸，进入上游或下游。实现原理：当船舶需要从上游高水位进入下游低水位时，关闭下游闸门，打开上游闸门，使船闸内水位与上游相同，然后上游船舶才能顺利入闸。然后关闭上游闸门，打开下游闸门，使船闸中的水位下降到大坝下游水位，使船闸中的船舶能够顺利地从下游闸门航行到大坝下游。水涨了，水就落了。客船可以通过两种方式通过三峡大坝。(1)方式1，让客船按部就班地通过五级船闸：当客船进入船闸闸室时，关闭闸门B后，应先关闭阀门，再打开。待闸室水位稳定后，开启A门，让客船行驶至上一闸室。锁利用了这个原理。(2)模式二，3000吨以下客船可由升船机直接垂直吊至上游：让客船进入升船机的载船厢，关闭厢门，由升船机直接将载船厢吊至上游，打开厢门让客船出载船厢。如果载船舱长100米，宽20米，载重1000吨，载船舱内有4000吨水，20

在开始的时候，在河道的中间拦截，分为南北两段，把中间的水抽干，修建一条河道，接下来在左右两边建起大坝，之后就往里面倒大量的石头。直到石头能覆盖在江面上把水堵住，长江的水就会绕道从另外一边的通道往下流，把水抽干就可以修大坝了，修建完成后接下来继续在另一边修建，直到两边都修建完成，很多大坝都是采用这样的方法修建的。枢纽布置枢纽主要建筑物由大坝、水电站、通航建筑物等3大部分组成。主要建筑物的型式及总体布置，经对各种可行性方案的多年比较和研究，并通过水力学、结构材料和泥沙等模型试验研究验证，均已确定。选定的枢纽总体布置方案为：泄洪坝段位于河床中部，即原主河槽部位，长483米，在泄洪坝段底部，均匀分布有22孔导流底孔弧形门，底坎高度为56米（或57米），弧门宽6米，高8.5米，22孔弧门分别由22台液压启闭机启闭，两侧为电站坝段和非溢流坝段。水电站厂房位于两侧电站坝段后，另在右岸留有后期扩机的地下厂房位置。永久通航建筑物均布置于左岸。

利用水利发电，把势能转换为电能。水力发电，研究将水能转换为电能的工程建设和生产运行等技术经济问题的科学技术。水力发电利用的水能主要是蕴藏于水体中的位能。为实现将水能转换为电能，需要兴建不同类型的水电站。水力发电系(Hydroelectric power)利用河流、湖泊等位于高处具有势能的水流至低处，将其中所含势能转换成水轮机之动能，再借水轮机为原动力，推动发电机产生电能。利用水力(具有水头)推动水力机械(水轮机)转动，将水能转变为机械能，如果在水轮机上接上另一种机械(发电机)随着水轮机转动便可发出电来，这时机械能又转变为电能。水力发电在某种意义上讲是水的位能转变成机械能，再转变成电能的过程。因水力发电厂所发出的电力电压较低，要输送给距离较远的用户，就必须将电压经过变压器增高，再由空架输电线路输送到用户集中区的变电所，最后降低为适合家庭用户、工厂用电设备的电压，并由配电线输送到各个工厂及家庭。水力发电的基本原理是利用水位落差 ，配合水轮发电机产生电力，也就是利用水的位能转为水轮的机械能，再以机械能推动发电机，而得到电力。科学家们以此水位落差的天然条件，有效的利用流力工程及机械物理等，精心搭配以达到最高的发电量，供人们使用廉价又无污染的电力。而低位水通过吸收阳光进行水循环分布在地球各处，从而回复高位水源。于1882年，首先记载应用水力发电的地方是美国威斯康辛州。到如今，水力发电的规模从第三世界乡间所用几十瓦的微小型，到大城市供电用几百万瓦的都有。

三峡大坝在宜昌市夷陵区。三峡大坝属于宜昌市夷陵区三斗坪镇的中堡村。此外，秭归县新县城城区茅坪镇、夷陵区三斗坪镇、太平溪镇、乐天溪镇这四镇统称三峡坝区，四镇已同三峡大坝主体连为一体。

As with many dams, there is a debate over costs and benefits. Although there are economic benefits such as flood control, clean hydroelectricity and navigation, there are also concerns about the relocation of people, siltation, loss of archaeological and cultural sites and the impact on regional ecosystem While the country benefits from gargantuan potential of electricity generation, we have to face up to various environmental conservation issues concerning geological and ecological environment along both river sides and whole upper reaches. The professional designers of the great dam now have to work out a practical way to prevent and remedy pollution effectively, which has already been the focus of world attention.

泄洪深孔工作闸门选用弧形门，孔口尺寸7m×9m（宽×高），设计水位175m，底坎高程90m，设计水头85m，据流体力学知识计算最大水流速度约35m/s，按这个标准算，每孔泄洪流量等于深孔截面积63平方米乘以流速35m/s，即为2205立方米每秒

短句吗？the three gorges dam is famous all over the world.

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world"s largest power station in terms of installed capacity (22,500 MW). In 2014 the dam generated 98.8 TWh of electricity, setting a new world record by 0.17 TWh previously held by the Itaipú Dam on the Brazil/Paraguay border in 2013 of 98.63.[4][5][6] But in 2015, the Itaipu power plant resumed the lead in annual worldwide production, producing 89.5 TWh, while production of Three Gorges was 87 TWh.[7][8][9]Except for a ship lift, the dam project was completed and fully functional as of July 4, 2012,[10][11] when the last of the main water turbines in the underground plant began production. The ship lift was complete in December 2015.[12] Each main water turbine has a capacity of 700 MW.[13][14] The dam body was completed in 2006. Coupling the dam"s 32 main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam is 22,500 MW.[13][15][16]As well as producing electricity, the dam is intended to increase the Yangtze River"s shipping capacity and reduce the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success,[17] with the design of state-of-the-art large turbines,[18] and a move toward limiting greenhouse gas emissions.[19] However, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides.[20] The dam has been a controversial topic both domestically and abroad.[21]
