| 摘 要： | 根据基坑工程施工实际情况，基于地下水渗流的基本规律，建立了基坑地下水渗流模型，通过有限元方法模拟了基坑地下水在不同的施工状态时的渗流情况。数值模拟结果表明：在不采取任何防水措施时，坑底会发生管涌，坑壁有水流出，不利于施工；设置挡土墙后，坑壁无水渗出，坑底发生突水；设置排水井后，可防止基坑突水和坑壁失稳。 |

| Abstract: | According to the seepage law of ground water,and when the execution situation of the project is also taken into account,seepage flow of foundation ditch ground water in different working states are simulated by finite element method,accordingly,some conclusions are drawn: if there are not any waterproof measures,piping effect will happen at the bottom of the ditch and much water will pour at the sides;after the retaining wall is built,there is no water at the sides of the ditch,but the bottom will destabilize;when drainage shaft is set around the ditch,the occurrence of the two situation above is prevented |
| Keywords: | foundation ditch project seepage flow finite element method ground water |
