| 摘 要： | 文章根据应力重塑的方法对开挖边坡进行处理,在坡面上施加荷载,使得边坡土体恢复到未开挖的稳定应力状态;并且利用大型有限元软件ANSYS来进行等效应力分析。对原状土体、开挖后的土体以及进行应力重塑后的土体内部的应力进行比较,得出开挖过程的应力损失并进行相应大小的应力补偿以达到应力重塑的目的,使边坡中的土体相当于在自重应力作用下进行工作。

| Abstract: | The method of remolding stress is applied to reinforce the excavated slope so as to resume the original stress condition of the soil mass of the slope,and the software ANSYS is used to analyze the equivalent stress. By comparing the original stress,the stress after excavation and the stress after the stress remolding,the stress loss due to the excavation can be obtained,and the stress to be compenstated can be known accordingly so that the remolding of the stress in the slope in excavation project can be carried out. |
