漳泽水库大坝结构安全分析

Analysis on structure safety of Zhangze Reservoir dam

本文根据漳泽水库2008年结构安全评价成果和运行期监测资料,对新旧坝体的沉降变形状态、大坝渗流和坝坡稳定进行了计算,分析结果表明:大坝各监测点倾度值均未超过临界破坏倾度值,坝面产生危险性纵、横向裂缝的可能性不大;大坝整体渗流状态正常,不存在渗流破坏问题;各种工况下大坝上、下游坝坡的最小安全系数均满足规范要求,不存在抗滑稳定问题。

In the paper, old and new dam settlement deformation status, dam seepage and dam slope stability are calculated according to structure safety assessment results and operation period monitoring data of Zhangze Reservoir in 2008. Analysis results show that the inclination value of all monitoring points in the same is not higher than the critical damage inclination value. The possibility for the dam surface to produce risky longitudinal and transverse cracks is low. Overall seepage condition of the dam is normal without seepage damage problem. The minimum safety coefficient on the upstream and downstream dam slopes of the dam can meet requirements of specification under all working conditions without anti-skid stability problem.
