摘要
基于强度折减法,本文针对非饱和土边坡在不同地下水位时,在是否考虑土体基质吸力两种不同情况下对非饱和土边坡稳定性开展了有限元分析。计算结果表明,非饱和土边坡的稳定性基质吸力有着密切的关系,当基质吸力随着外界环境发生变化时,边坡的稳定性也随着发生改变。
Based on strength reduction method, this paper analyzes stability of unsaturated slopes with different groundwater level. The results show there is a closed relationship between matric suction and safety factor of unsaturated slopes, when matric suction is changeable with different external con- ditions, the stability of unsaturated slopes is also changeable.
