| 摘 要： | 针对目前在边坡稳定分析中,常规的数值计算方法和极限平衡法都是利用边坡的整体安全系数来表征,不能反映边坡各部位稳定性的不同,进而无法将边坡稳定性与滑动机理联系起来。本文根据建立的Ansys有限元正分析模型先计算应力场,然后求解出模型各点处的安全系数值,再利用Ansys软件的后处理功能绘制出模型的安全系数等值线云图,最后对边坡的稳定性作出综合评价。

| Abstract: | At present,in the analysis of slope stability,both the limit equilibrium method and the numerical calculation method only use the overall safety factor as a quantitative index,which can't reflect the difference of the stability of each part of the slope,and then can't link the stability of the slope with the sliding mechanism.In this paper,the safety factor of each point is calculated according to the stress field calculated by the finite element method,and then the contour map of the safety factor is drawn by the post-processing function of Ansys,and then the stability of the slope is analyzed and evaluated. |
