摘要
着重探讨了不同浸润线高度条件下边坡的安全系数、塑性区范围等指标的变化趋势,针对典型算例进行了详细计算分析,结果发现:浸润线水面较高时,安全系数较小;浸润线水面每下降1 m,安全系数约增加0.1;当浸润线水面过低时,与无水工况下的安全系数一致。
The paper mainly explores the change tendency for some indexes,such as the safety coefficient of the side slopes and the scope for plastic zones with various heights of the saturation line,has the detailed calculation analysis according to the typical calculation cases,and finds the safety coefficient is a little small when the saturation line is high,the safety coefficient can increase by 0.1 when the saturation line is lowered by 1 m,the safety coefficient is consistent with the one of non-water condition when the saturation line is too low.
