2、设施为斜卧管，浆砌条石结构，有渗漏，且运行管理不便。本次设计的主要内容为：通过对新春水库复核基本资料为水文设计洪水复核、洪峰流量以及溢洪道最大泄洪能力复核、大坝渗流稳定分析、除险加固方案设计、施工组织设计等。通过水文方面计算，试算出设计和校核水位，最后进行溢洪道最大泄流能力复核，另外通过大坝的渗流稳定分析确定大坝是否存在险情并采取有效的工程措施，从而使大坝达到除险加固的目的。关键词：水文计算；稳定分析；渗流分析；稳定分析；除险加固 华北水利水电学院毕业设计 第 页 共 页2 AbstractXinChun reservoir is located in Sichuan Jiangyou Don

The main river above the dam site long 5.17km, channel slope 12.53 . Dam has an influence of a populatio
4、n of about 800 people and 1200 acres of farmland. Project started construction in 1973 and put into operation in 1975. It is a mainly for irrigation, flood control, water supply, farming and the small overall efficiency (2) reservoir.The 5.12 of the reservoir as a result of the earthquake caused dam
5、age to some extent, such as: (1) there are a number of cracks in the dam; (2) leakage downstream dam slope is not welcome for water protection, water rinse dig grave; top of the dam is not hardened, not conducive to project management and dam safety. (3) the original drainage facilities decumbens tu
