Downstream energy dissipation and scour prevention design method for steel dam gate
The invention discloses a downstream energy dissipation and scour prevention design method for a steel dam gate, and the minimum length of a downstream energy dissipation structure of the steel dam gate is determined according to the farthest distance of flushing and smashing of an overflow nappe of the steel dam gate. The actual impact rolling area range can be included, the situation that the lower portion of the tail end of the steel dam gate bottom plate is emptied is avoided, the length of the stilling pool or the plunge pool is set according to the value, the engineering construction amount can be reduced, meanwhile, the construction cost is reduced, and the safety of the energy dissipation structure behind the gate can be ensured.
本发明公开一种钢坝闸下游消能防冲设计方法，根据钢坝闸溢流水舌冲砸的最远距离，确定钢坝闸下游消能结构的最小长度。能够将实际冲击翻滚区范围包括在内，避免钢坝闸底板末端下方被掏空的情况，根据该值设置消力池或水垫塘长度，可以减少工程施工量的同时，降低了施工成本，并且可以确保闸后消能结构的安全性。
