考虑到大跨度液压下翻转式卧倒门受力状态复杂,有必要采用三维有限元对其进行空间结构复核的情况,通过对不同设计工况的建模计算及对其控制工况的探索,指出当闸门倾斜一定角度挡水或过水时,根据挡水方向的不同,自重起着不同的作用,在闸门设计时应予以充分考虑。
攷慮到大跨度液壓下翻轉式臥倒門受力狀態複雜,有必要採用三維有限元對其進行空間結構複覈的情況,通過對不同設計工況的建模計算及對其控製工況的探索,指齣噹閘門傾斜一定角度擋水或過水時,根據擋水方嚮的不同,自重起著不同的作用,在閘門設計時應予以充分攷慮。

Taking into account the comolicated force of the large-soan downflao hydraulic gate. It’s necessary to check the structure state aooly-ing the three-dimensional finite element. According to the different conditions its calculational model is created,and the control condition is re-searched . When the gate slooe determinated angle whether flooding or controlling,it is necessary to account the self-weight in the designing of the gate according to the different control direction because of its different effect.
