| 摘 要： | 本文对宝鸡市簸箕山塬边老黄土滑坡体进行三向渗流数值计算，针对三向渗流计算中排水孔孔径小，传统方法难以模拟、计算精度难以保证等情况，提出三向渗流计算中排水孔和排水洞模拟的约束条件法，并验证方法的正确性，分析方法的适用条件。对滑坡体渗流计算表明：设置排水洞和排水孔可以有效地降低滑坡体的地下水位，对提高滑坡体的稳定性极为有利。 |

| Abstract: | The seepage characteristic of loess landslide body at Bojishan in Baoji city has been computed by using 3D numerical method, and the problems of drainage culvert and drainage holes simulation in 3D numerical seepage analysis are solved. It is difficult to do 3D numerical seepage analysis, because the diameter of drainage holes is very smaller than the landslide body. The groundwater level of landslide body is depressed by setting drainage culvert and drainage holes in it. The computed results show that setting drainage culvert and drainage holes can effectively depress the groundwater level of landslide body, which is in favor of increasing the stability of the landsliding body. |
