摘要

采用双平面滑动刚体极限平衡法计算边坡稳定性分析模型

考虑了水压力、地震动荷载的作用并进行加固研究

探讨了结构面力学参数敏感性分析。结果表明

水压力是边坡破坏最重要的影响因素

地震动荷载对边坡稳态的作用是比较显著的;应当将总锚固力的标准值提高到2920 kN

才能满足边坡稳定的要求;锚固角为25°时

锚固效果较好又相对经济;结构面力学参数1φ对边坡稳定性没有影响

参数c1、c2和2φ增大有利于边坡稳定

这三个参数的影响程度从小到大依次增强

但是总的来说影响并不大。本文研究方法和成果可以为改善工程施工提供依据。

Abstract

A model based on limit equilibrium analysis of rigid body with double sliding plane for calculating rock slope stability is proposed in the paper.The influences of hydraulic pressure and earthquake load are considered.The anchorage research is carried out.The sensitivity analysis of mechanical parameters of structural plane is analyzed.It is shown that the hydraulic pressure is the most important effect to the failure of slope and the effect of earthquake load is also remarkable.The rock slope is safe on condition that the total anchoring force is enhanced to 2 920 kN.Moreover

both anchorage effect and economic benefits are achieved when the anchoring angle is 25°.The parameter φ1is independent of the slope stability

but the parameters of c1、c2and φ2which are improved are helpful and in a increasing order.However

the influence grade is small.The obtained results can offer criteria to improve the practicial construction of engineering.
