| 摘 要： | 用有限元程序在呼和浩特至集宁高速公路做边坡稳定分析,将应力-应变引入传统的弹塑性力学,根据计算得到的应力场来计算各点的安全系数,在不假定滑动面的情况下,利用安全系数的理论,绘出安全系数等值线图,其安全系数就是边坡的安全系数,从而,理论确定最大的滑动面经检验与实际相吻合。 |

| Abstract: | The analysis on high slope stability for Hohhot to Jining Expressway was made with ANSYS software,and the stress-strain relation is introduced to the traditional elastic-plastic mechanics.The margin of safety at different point is computed by using the stress field obtained from computation.Under the conditions without assumed slide surface,the isograms has been drawn by using the theory of safety factors,and this factor is that of slope,thus determining the maximum slide surface by theoretical analysis being consistent with actual situation through examination. |
