某水库浆砌石重力坝溢流坝段抗滑稳定分析

Anti-Sliding Stability Analysis of Spillway Dam Section of Reservoir Slurry Masonry Gravity Dam

对于浆砌石重力坝,其坝体抗滑稳定不仅应计算砼垫层与基岩接触面的稳定,还应计算砌石体与砼垫层接触面的稳定以及砌石体之间的稳定。为提高大坝抗滑稳定,大坝坝址宜选择在坝基岩体接触面倾向上游处,坝基宜设置防渗帷幕及排水孔,坝体设置排水管。

For the mortar masonry gravity dam,the stability of sliding resistance of the dam body should be calculated not only for the stability of the contact surface between the concrete cushion and the bedrock,but also for the stability between the masonry body and the concrete cushion.In order to improve the anti-sliding stability of the dam,the dam site should be selected in the upstream of the contact surface of the dam foundation rock mass,impervious curtain and drainage hole should be set up in the dam body,and drainage pipe should be set up.
