溢洪道断面的设计

Designs of Spillway Section

通过对溢洪道宽度和淤地坝坝高的优选 ,找到了二者的最佳组合 ;并通过用迭代法求临界水深和正常水深 ,使求水面曲线的方法简化 ,依据此方法求平均水深 ,据此设计溢洪道侧墙高度 ,使工程便于施工且费用最小。为溢洪道的设计、施工及预算造价提供了科学依据。

Though optimization of broad of spillway and dam height of silt dam，their optimum combination was found；And It makes the method of reckoning curve of the surface of water simple to calculate critical and normal water depth by the method of repeated，according to the above method,to calculate average water depth，by this it is designed to height of side wall of steep section of spillway，this make construction convenient and fee smallest.These provided scientific basis for design，construction and budget cost of spillway.
