腊寨水电站边坡稳定性分析研究

Stability Analysis of Slope at La-Zhai Hydroelectric Power Project

水电站建设不可避免地形成一些高边坡,而这些边坡的稳定性又是影响水电站建设能否顺利进行的关键问题之一。腊寨水电站岩质边坡一般地质条件复杂,影响因素非常复杂,根据地质报告难以确定坝址边坡的稳定性。文章依据地质资料,对库区岸坡的稳定性做了定性的分析。同时结合刚体极限平衡法对影响水电站安全的坝址边坡的稳定性进行定量分析。在此基础上,提出对应的边坡治理措施,为腊寨水电站边坡的治理提供理论参考。

High - steep rock slope have formed in hydroelect power project, but the slope have affected the work of hydro - power station. With complex geological condition of high rock slope at the dam area, stability analysis of slope is conformed by the geological data. In the paper, the problem is solved though rigid body limit equilibrium method based on the geological texture. And analysis defor marion models have been built. In light of deformation models, the rigid body limit equilibrium method is used to calculate , analyze and evaluate the stabilities of the slope at dam areas. It provides scientific basis for administering the slope.
