有限元在岩石高边坡应力和位移分析中的应用

Application of Finite Element Method to the High Rock Slope Stress and Displacement Analysis

在详细研究分析温州市青少年活动中心的岩石高边坡的工程地质勘测资料的基础上,选择了1#和2#两个断面进行了有限元模拟,并以图形的形式显示计算结果。结果说明:在斜坡近坡面一定范围内的岩体中,发生应力重分布作用,最大主应力、最大剪应力及最小主应力在坡脚有一个明显的应力集中带,水平位移及竖向位移很小,整个坡体的稳定性比较好,仅局部有一小部分拉破坏区分布。

Finite element method has been developed in recent year, it is an effective method to solve the questions of geotechnical. Based on the study of the characteristic of the deformation and failure of the slope, there two vertical-sectional sizes were analyzed by the method. The outcome is indicated in pictures, witch suggested that the stress of slope was redistributed to a certain extent. And the maxinum primary stress, the mininum primary stress and maxinum shear concentrate at the base of the slope and so on.
