| 摘 要： | 通过数值模拟,研究了某边坡在两种降雨强度下坡体内基质吸力的变化情况,并对边坡的稳定性进行了分析,结果表明:在降雨强度恒定情况下,随着降雨的持续,边坡土体安全系数减小,但降雨停止后,又逐渐恢复到原来的状态;当降雨强度不同时,降雨强度越大,边坡土体稳定性受时间作用越显著。

| Abstract: | Through numerical simulation research,a landslide in two kinds of rainfall intensity in the change of the matric suction,and the landside stability were analyzed.The results show that the rainfall intensity with constant rain continued,landslide soil safety coefficient reduced,but after rain stopping,the landslide gradually restored to the original statement;when the rainfall intensity is different,the greater rainfall intensity,the more significant effect of stability of landslide soil by the time. |
