| 摘 要： | 文章对病险水库除险加固设计中,当堰坎厚度8与堰顶水头H之比大于10时,仍按宽顶堰计算溢洪道泄洪能力来进行洪水调节计算存在的问题进行分析,同时对溢洪道底坡为缓坡,溢洪道内水流为缓坡均匀流时,溢洪道过流能力与水库水位关系计算存在的问题进行分析,并以实例对比说明计算错误对工程运行的影响。

| Abstract: | In the design of danger control and reinforcement of those dangerous reservoirs,the paper analyzes the existing problems when he ratio of the thickness of a reservoir dam 8 to the weir crest water head H is more than 10,the flood carrying capacity of the spillway is calculated on the base of broad crest weir to calculate flood regulation.Meanwhile,the paper analyzes other existing problems when bottom slope of the spillway is viewed as gentle slope and water flow in the spillway is uniform flow of gentle slope,the relation between uniform flow of the spillway and reservoir water level is calculated and expounds the impact of wrong calculation on engineering operation with a real case. |
