漳泽水库大坝结构安全分析与评价

漳泽水库大坝于1960年建成,1989年至1995年全面改建后,大坝加高5m。加高后新坝体的结构安全是历次安全评价重点关心的问题。本文结合漳泽水库2008年结构安全评价成果和运行期监测资料,系统分析了新旧坝体的沉降变形状态,并对大坝渗流和坝坡稳定进行了计算分析,结果表明:目前水库大坝新旧坝体的沉降均达到稳定状态,坝面发生危险性裂缝的可能性很小,上下游坡面的稳定安全系数均满足规范要求,不存在抗滑稳定问题。

get a jersey reservoir dam was built in 1960, from 1989 to 1995, the comprehensive reconstruction, the dam heightening 5 m. After heightenning dam of new structure security is a key concern of the various safety evaluation. 2008 this paper get a jersey reservoir structure safety assessment results and the run-time monitoring data, analyzed the new settlement deformation of the dam body, and the dam seepage and dam slope stability calculation and analysis, the results show that the the settlement of the new and old reservoir dam dam are reaching a stable state, the dam face the possibility of fracture risk is very small, upstream and downstream slope stability safety coefficient can satisfy the requirements of specification below, there is no problem of stability against sliding.
