宁溪水利枢纽毕业设计
摘要:宁溪水库枢纽为江北河开发的第一梯级,流域面积共3200km2。该工程开发任务以发电为主,兼顾防洪。设计中,基于给定的地质及水文气象等资料,首先进行了重力坝的坝型选择,选取了混凝土实体重力坝坝型;然后进行了水库水位调洪演算,,;还对挡泄水建筑物的剖面进行设计,,采用表孔溢流,并对挡水坝段进行了抗滑稳定分析及坝体应力分析,结果均满足要求;最后还对大坝进行细部构造设计,并阐述了关于消能防冲的方案。

Abstract:NingXi Reservoir is the first step of Jiangbei river development ,the basin area of project development, giving priority to the task to power of flood design of this project is based on the data of geological and hydrological and meteorological which is given, first select the solid concrete gravity dam to be the type of gravity, and then make the calculus of floodind the reservoir water level ,the result is the design flood level and Check flood level ; also design the water discharge structure with surface hole which size overflow and water retaining structure to determine the dam height is and water retaining dam stability analysis for the dam and stress analysis, the results are satisfied Requirements; Finally, detailed structural design of the dam, and elaborated on the energy dissipation of the program.
Keywords:Ground-handling project layout concrete gravity dam section
the load calculation stability analysis and stress analysis
