摘要:
从滑坡变形监测规律出发结合有限元强度折减法，对重庆市涪陵区植物油厂滑坡建立了一种有限元特征点位移监测分析法，研究该滑坡的变形破坏过程。结果表明，植物油厂滑坡属于牵引式滑坡，处于顺层蠕滑初始阶段，滑坡中前部变形比较强烈；从位移与折减系数的关系曲线得出滑坡在达到极限平衡状态之前，存在一个明显的变形加速过程；通过有限元强度折减法和不平衡推力法的综合分析，得滑坡整体稳定系数F=1.15，中后部局部剪出体稳定系数为Fr=1.20，滑坡安全储备不足。
Abstract:
According to landslide deformation rule and strength reduction method, a finite element feature point analysis method is built. Using this method to study vegetable oil plant landslide deformation and damage process, the conclusions are reached as follow: Vegetable oil plant landslide belonging to Traction landslide, in the initial stage of bedding slipping; the front part of landslide deformation relatively large; the landslide reached the limits of balance.From the curve of ΔX/ΔFsr by strength reduction method, there is a significant deformation accelerated process, the safety factor of the overall landslide is F=1.15, the safety factor of dangerous rear local landslide is Fr=1.20.
