工程计算说明书1调洪演算选定溢流堰堰顶高程H1，取为337米。取起调水位为正常水位，即H1=345米。选定调洪过程：起调水位为堰顶高程，闸门全开，作为无闸门情况对待，但设计洪水情况在下泻洪水流量2800 m3/s时，则控制闸门开度使下泻量保持2800m3/s。方案：设计工况堰顶高程取337m ，堰宽40m ，闸门共5孔 ，t=14400秒时 （1）

有关，根据m=f（H/Hd），查得从345米开始，即H=345-337=8米开始，对应的每个m值。水位水深H流量系数m350130.514349120.508348110.502347100.49434690.48634580.48同时考虑水轮机引用流量（由于不可能总是三台机组同时工作，故只考虑一台机组引用流量），得出该枢纽在不同堰宽（8*5，14*3，9*5）的下泻洪水流量。如下表：水位水深m流量36m流量42m40米（5*8）
