摘要:
蚀变带的存在对边坡稳定具有不确定性的影响,为充分认识蚀变带对边坡稳定性影响,建立多种工况下的边坡分析模型,分析结果表明:当蚀变带处于滑坡体内部或者远离滑坡体时,蚀变带的存在会增大或不影响边坡安全系数;当蚀变带与滑坡带相交时,边坡安全系数减小。同时,蚀变带倾角对边坡安全系数影响具有临界性。研究成果可以为含蚀变带等软弱夹层的边坡稳定性分析提供一定的依据。
Abstract:
The alteration zone has uncertainty effect on the slope stability. In order to fully understand the effect of alteration zone on slope stability, the slope stability model under various conditions was established, and the analysis results showed that: When the alteration zone was inside or far away from the landslide body, the existence of the alteration zone would increase or not affect the slope safety factor. When the alteration zone intersected the landslide zone, the slope safety factor would decrease. At the same time, the inclination of the alteration zone has a critical effect on the slope safety factor. The research results could provide certain basis for slope stability analysis of soft inter-layer including alteration zone.
