摘要:
为了准确地分析边坡的稳定性,根据有限差分强度折减法原理,运用弹塑性理论及相关理论构建求解边坡稳定性安全系数的迭代步骤模型.边坡失稳的判据主要是联合采用塑性区贯通性和速度矢量图来判断,并结合实例进行了分析.研究结果表明:有限差分强度折减法不仅可以准确得到边坡安全系数而且可以描绘出边坡的变形过程及其滑动面形状.
Abstract:
The purpose of this paper is to analyze the stability of the slope accurately. based on the strength reduction finite difference method theory, the elastic\|plastic theory and related theories were used to construct the model of solving steps of slope stability. The criterion for slope instability was obtained by combined use of the breakthrough of plastic zone and velocity vector diagram. and then the strength reduction finite difference method was applied to an engineering case. The analysis results show that this method can not only get the accurate slope safety factor ,but also depict the slope of the deformation process and the shape of the sliding surface.
