| 摘 要： | 基于重庆库区工程弃土在经历极端降雨条件下达到不同的饱和度,应用GEO-SLOPE软件对其进行计算,采用非饱和土强度理论对其结果进行分析,结果表明:库区内工程弃土天然含水量较小,一定量的前期降雨量有利于增强其稳定性,但是在极端降雨情况下,高强度的降雨使土体迅速达到饱和,低强度且长时间的降雨使土体经历较长的时间达到饱和,最后由于基质吸力丧失,稳定性降低,导致滑坡。

| Abstract: | Based on the different degree of saturation of the Engineering soil which experienced extreme rainfall in the reservoir area of Chongqing,using the large finite element analysis software GEO-SLOPE to simulate,applying strength reduction to analysis the stability of the deposits.The results show that: due to the natural water content,a certain amount of rainfall in the early stage will reinforce its stability,but under the extreme rainfall,the high-intensity rainfall makes the deposits to achieve saturation ... |
