摘要
挑坎角度对水库工程的整体质量会造成直接影响,通过试验方式对水库工程挑坎角度进行适当优化,从而选择一个合理挑坎角度,保证水库工程能够满足应用需求。以响水水库为例,通过对两种挑坎角度优化试验进行分析可以发现,相比于设计方案和挑坎角度(0°)方案,挑坎角度优化方案二(10°挑角)中挑坎型式较为合理,方案二既将水舌挑离下游地质薄弱区域,又可兼顾两岸坡脚的冲刷,因此,在响水水库工程中采用方案二,提升水库工程的整体质量,满足应用需求。
The angle of flip bucket will have a direct impact on the overall quality of the reservoir project.The angle of flip bucket of the reservoir project will be appropriately optimized through the test method.A reasonable angle of flip bucket can be selected to ensure that the reservoir project can meet the application needs.Taking Xiangshui Reservoir as an example,this paper analyzes the two kinds of pick angle optimization experiments.The result is that the scheme 2(10°pick angle)is reasonable,which is compared with the design scheme and the pick angle(0°)scheme.The scheme 2 not only lifts the water tongue away from the weak geological area downstream,but also takes into account the erosion of the slope foot on both banks.Therefore,the scheme 2 is adopted in the Xiangshui Reservoir Project.This scheme can improve the overall quality of the reservoir project and meet the application requirements.
