根据膨胀岩土的工程特性,通过对单面开挖和填土边坡受膨胀力的状态进行了分区,分析了受力模式,采用极限平衡法中的Fellenius法(瑞典圆弧法)和Bishop法(简化Bishop法)分别计算边坡稳定系数,并确定是否需要采取工程措施。
According to the engineering characteristics of expansive rock and soil, the conditions of single-sided excavation and filling slope are expansive, and the stress mode is analyzed. The Fellenius method (Swedish arc method) and Bishop The Law (Simplified Bishop Method) calculates the slope stability factor separately and determines if engineering measures need to be taken.
