大坝渗流稳定及坝坡稳定计算分析

Calculation and analysis of dam seepage stability and dam slope stability

以楼庄子水库粘土心墙坝为例外,对粘土心墙坝坝体结构渗流稳定及坝坡稳定进行了计算分析。采用目前较为广泛的极限平衡原理进行分析,得出楼庄子水库粘土心墙坝坝体心墙料及坝料,在设计工况、校核工况下均不会发生渗透破坏;不同运行工况下,大坝上下游坝坡均满足抗滑稳定要求,上下游坝坡均稳定。分析成果为大坝渗流稳定及坝坡稳定提供了理论依据。

Taking the clay core wall dam of Louzhuangzi Reservoir as example,dam body seepage stability and dam slope stability were calculated and analyzed by the limit equilibrium principle widely used based on which core wall and dam materials were determined;and it is concluded that seepage failure will not occur under design and check operating conditions,upstream and downstream dam slopes both satisfy the requirements for stability against sliding under various operating conditions.
