重度增加法在砂黄土边坡稳定性分析中的应用

On the application of the gravity increasing method in the stability analysis of the sandy loess slope

分析了有限元重度增加法的基本原理,考虑非关联流动法则,用重度增加法对砂黄土质边坡进行了稳定性分析,用一个步长较小的区间描述了安全系数,从而避免了关于破坏标准的人为不确定性,建议该步长为0.2。

The paper analyzes the basic principle of finite element gravity increasing method, indicates to adopt the stability analysis of sandy loess slope by the gravity increasing method after the consideration on the non-associated flow rule, and de.scribe.s the safe coefficient of the interval with smaller step, so as to avoid the artificial uncertainty by violating standards and the step as 0.2 is suggested.
