| 中文摘要: |
| 基于饱和—非饱和渗流理论，结合某高填方边坡，通过对研究区域(对称)的二维简化，利用有限元软件分析降雨条件下边坡的渗流特性及植被、水平排水孔等相关工程处治。研究结果表明:植被的覆盖能有效降低坡内孔隙水压力，雨后变形降低14.3%；排水孔的合理布设能有效排除坡内积水，相对渗透系数宜取值2 000左右。 |

| Based on the saturated unsaturated seepage theory, combined with a high fill slope, through the study area(symmetric)of two-dimensional simplification, the finite element software was used to analyze the rainfall conditions under slope seepage characteristics and vegetation, horizontal drain hole related engineering treatment. The results show that the vegetation cover can effectively reduce the pore water pressure in the slope, and the deformation can be reduced by 14. 3% after the rain, and the drainage hole can effectively eliminate the water in the slope, and the relative permeability coefficient is 2 000. |
