Let you know how the steel gate hydraulic dam holds back the flood
讓你了解鋼閘門液壓壩是怎么擋水泄洪的

1. When stable, in the normal use of steel gates and hydraulic DAMS, the upstream water level of the interception is relatively high, which leads to a large water level difference between the upstream and downstream steel gates, and the phenomenon of excessive horizontal pressure will occur, thereby making the sluice move in the downstream direction.
1.穩定時，在正常使用鋼閘門、液壓壩時，攔截上游的水位比較高，這樣就導致鋼閘門上游和下游之間產生很大的水位差，會出現水平壓力過大的現象，從而使水閘向下游方向移動。

In order to stabilize itself, the steel gate weight to meet the rules.
要想穩定自身，鋼閘門重量要滿足的規則。

In addition, after the completion of the hydraulic dam and steel gate, if there is no water block or no water period in normal use, it will produce a large vertical load, so that the actual pressure of the foundation will greatly exceed the bearing capacity of the foundation, resulting in foundation deformation or the phenomenon of the foundation soil being squeezed out.
另外，液壓壩、鋼閘門在建成以后，如果還沒有擋水或者是在正常使用的情況下遇到無水期，就會產生很大的垂直荷載，這樣基底的實際壓力就會大大超過地基能夠承受的承載力，從而出現地基變形或者是出現閘基土被擠出的現象，

This can easily cause the danger of sliding the sluice and the foundation.
這很容易造成水閘與地基出現滑動的危險。

Therefore, the area of the foundation must be guaranteed when the hydraulic dam is built, so as to effectively reduce the compressive stress of the base.
所以，在修建液壓壩時必須保證基礎的面積，這樣才能有效的降低基底的壓應力。
