| 摘 要： | 利用FLAC3D对边坡进行数值模拟,分别对对沙子岭边坡降雨前及降雨后的边坡变形过程进行模拟,显示处了边坡的变形发生在基岩中软弱层的位置,因受地表水体入渗造成软弱层软化现象,而导致力学性能迅速降低,坡体并沿着物质分异面发生剪切破坏的过程,该模拟过程与边坡实际变形基本一致,反映了FIAC3D在边坡变形预测预报中具有较好的应用前景。

| Abstract: | It does numerical simulation to the slope by FLAC3D,simulates the slope deformation process before and after rain,reveals the location where the deformation of slope in the soft layer of bedrock,displays the process that the Degradation of soft layer seeped by surface water,causes the mechanic property decrease quickly,shear failure happens to the slope along the material boundary.The simulation is almost the same to the actual deformation of the slope,reflects the application prospecting of FIAC3D in the slope deformation warning. |
