| 摘 要： | 针对路堑路基,采用有限元方法计算分析了降雨入渗情况下,不同地下水位和是否设置边缘渗沟的路基与路面中的压力水头,通过分析得出：在地下水位高和雨水量大的地区设置渗沟是非常有必要的,其他地区或地段设置渗沟也是有益的。

| Abstract: | Aiming at cut roadbed,finite element method is adopted to analyze pressure water head of the road surface at the circumstance of rainfall infiltration,different ground water level,and whether edge percolation trench of roadbed have been established.We concluded that： It is necessary to establish percolation trench in places where high ground water level and large rainfall exist.Percolation trench in other regions or district is also beneficial. |

| Keywords: | rainfall infiltration ground water road surface cut roadbed pressure water head |
