喜河水电站右导墙深层抗滑稳定性分析

Stability Analysis of Right Training Wall at Deep Layer of Xihe Hydropower Station

喜河水电站右导墙紧临厂房基坑,基础围岩裂隙发育,深层抗滑稳定问题比较突出,倾向基坑的缓倾角断层的出露增加了基础边坡处理的难度。设计过程中根据枢纽布置和基础地质特性,分段建立计算模型,进行深层抗滑稳定性计算分析,并根据计算结果采取了相应的工程处理措施。

The right guide wall cheek by jaw with footing groove of power station of Xihe project. The crack developed in adjacent rocks, thus there is evident problem of anti slid stability. The angle of fault declination to the footing groove increases treatment difficulty. Based on the pivot layout and foundation geology feature, a computation model is established according to different sections. The stability computation is conducted, by which the engineering countermeasures are put forward.
