基于MARC强度折减法在降雨条件下边坡稳定性分析

Analysis on slope stability under rainfall condition based on MARC strength reduction method

通过查阅文献和计算对降雨条件下抗剪系数减小和重度增加两个因素对边坡安全系数影响的比较,得出前者对边坡稳定性的影响更显著,应用MARC程序模拟了在降雨条件下,雨水从上而下入浸对边坡安全的影响,得出随着雨量的增加安全系数减小,并进行了分析,其研究结果可为边坡工程的设计和防治提供一定的参考。

Through the slope safety coefficient influence comparison of shear coefficient decrease and weight increase two factors under rainfall condition by the literature review and calculation,gained that the former had more obvious influence to slope stability.Application of MARC simulation the influence of rainfall from top to down dip to slope safety under rainfall condition,gained that with the rainfall increased,the safety coefficient decreased,and analyzed,the results could provide certain reference for design and prevention of slope engineering.
