基于ABAQUS的凉水井滑坡稳定性分析

Analysis on Landslide Stability based on ABAQUS

利用大型有限元软件ABAQUS对凉水井滑坡段进行了数值模拟分析,通过应力应变场的云图分析,确定边坡的最危险潜在滑动面。依据强度折减法的原理,利用ABAQUS定义场变量为强度折减系数值,通过改变场变量实现摩擦角和粘聚力的折减,得出边坡稳定性安全系数,并对滑坡的整治措施提出建议。

Liangshuijing Landslide is analyzed through numerical simulation with large finite element software ABAQUS and the most dangerous potential sliding surface of the slope is confirmed through analysis on cloud atlas of the stress and strain field. Depending on the principle of strength reduction method, the field variables are defined as the value of strength reduction factor with ABAQUS so that the reduction of friction angle and cohesion could be realized by changing the field variables, and then the safety factor of the slope stability could be obtained. In addition, the advice against the landslide treatment is proposed.
