Abstract: According to the execution situation of the project, the constitutive model of rock and soil and the seepage law of ground water are taken into account, a new mechanics model of the ditch is established , seepage and the stress field of foundation ditch in different working states are simulated by finite element method. Accordingly, some conclusions are drawn: during the process of excavation, deformation of the soil around the ditch occurs, the soil at the bottom of the ditch swells, at the corner, there exists a stress concentration, this point is a vulnerable area, it should be treated with caution. In addition, with the precipitation of the ditch, the deformation of the rock and soil around the ditch will increase gradually, this will affect the safety of the retaining wall and the building near the ditch, therefore, during the construction of the ditch, precipitation should be controlled cautiously.

Key words: foundation ditch project, seepage, finite element method, ground water, coupling
