摘要： 富水地质条件下的地下开挖工程普遍存在渗流问题，研究其内部渗流场的作用规律，了解渗流场作用下工程结构的受力状况十分必要。通过对滠水河穿越工程用FLAC3D软件数值模拟进行分析，结果表明,在渗流场作用下围岩与顶管的位移和应力显著增加，因此在进行地下开挖及支护时应该充分考虑渗流作用。

Abstract: The seepage problem is a prevailing issue in the excavations under saturated conditions. For the geotechnical projects, it is very important and necessary to study the seepage field properties and the stress strain status under the seepage actions.  This paper presents the numerical simulation results of a pipe line project cross the Sheshui River by using FLAC3D software. The results indicate: under the seepage action, the deformation and the stress have a significant increase in both the surround rock mass and the jacked pipe line. Therefore, the seepage action should be considered for the excavation support design and construction.
