This project mainly for power generation,.The design of this project is based on the data of geological and hydrological and meteorological which is given, first select the roller-compacted concrete 2下载后可任意编辑gravity dam to be the type of gravity, and then make the calculus of reservoir flood routing by the existing flood hydrograph, which the design flood level is 1478.35m and the check flood level is 1480.26m, also design the water discharge structure with surface hole to overflow which size is 16×15m, conducted a profile design for gravity to determine the dam is 106m.For nonoverflow dam monolith, carried out stability analysis and the corresponding stress analysis, and design cross section, energy dissipation and erosion scheme for overflow dam monolith, the results meet requirements.Finally, conducted a detailed structural design and foundation treatment.关键词: 碾压混凝土重力坝 调洪演算 剖面设计 抗滑稳定分析 应力分析 消能防冲方案 细部构造 地基处理Keywords: the roller-compacted concrete gravity dam reservoir flood routing3下载后可任意编辑profile design stability analys...
