分流河段布设水工建筑物时的水力计算方法

The hydraulic calculation method applies to the hydraulic structure laying in the split flow river section

水工建筑物布设在分流河段区域内,其过流、消能结构形式及水力计算方法比较复杂。针对分流河段、水位条件变化条件,如何求得各分流建筑物的过流能力及建筑物上下游水位的关系,提出了一种计算方法,为今后在分流河段布设水工建筑物时的水力计算提供借鉴和参考。

Since that hydraulic structure is layed in the split flow river section,its overflowing, energy dissipation structure and hydraulic calculation method are complex.According to the split flow river section and the condition for water level change,the paper puts forward a calculation method on acquiring the flow capacity of each structure and the relation between its upstream and down stream,which provides reference for further similar cases.
