| 摘 要： | 通过数值模拟软件MIDAS/GTS对在加固前后降雨入渗对边坡稳定性的影响进行研究,可以得出：加固前坡体在天然状态下开挖稳定性较好,在降雨入渗条件下随着降雨强度、降雨持时的增加,边坡的水平位移不断增加。采用锚喷护面后,即使发生暴雨,边坡的最大水平位移仅为25mm,最大垂直位移为15mm,此时计算出的安全系数为1.28,边坡稳定。

| Abstract: | Influences of rainfall infiltration on the stability of slope before and after the reinforcement were studied respectively by the numerical simulation software MIDAS/GTS,and some conclusions can be drew: before the reinforcement,slope is stable when it is excavated under the natural conditions,but in the rainfall condition,with the increasing of the rainfall intensity and duration,the horizontal displacements of the slope is increasing.Ifbolt-shotcrete rockbolt support is adopted,the maximum horizontal disp... |
