皂市水电站堆积体边坡稳定性及加固措施研究

摘要

The side accumulation body of Zaoshi hydropower station is close to the power house, and its stability directly threats the construction safety and the power house structure. In consideration of the uncertainty of the accumulation body and contacted foundation rock mass, firstly, the safety coefficient of the accumulation body for different parameters and possible instability mode are researched by strength reduction method to select reasonable parameters, and on this base, the side -slope stability under different conditions and the possible instability modes as well as different reinforcement effectiveness are analyzed and researched.%皂市水电站堆积体边坡临近厂房机组段,其稳定性直接影响到施工安全并对厂房建筑物构成威胁.鉴于堆积体及其与基岩接触面部分岩石力学参数的不确定性,首先采用强度折减法研究不同参数取值情况下边坡的安全系数及可能的失稳模式,选取合理的堆积体参数.在此基础上,对在不同工况下的边坡稳定性、可能的失稳模式以及不同加固处理方案的效果等进行了分析和研究.
