Abstract: Based on the generalized Darcy’s Law which can describe the anisotropy of infiltration tensors and the relative permeable degree theory related to relevant fundamental seepage theory of a fractural rock mass, 3-D nonlinear finite element method was applied to simulate the process of three dimensional saturated-unsaturated and unsteady percolation diffusion in the high slope of the Three Gorges Project(TGP) permanent shiplock during continuous rainfall. The distribution of infiltration fields in the slope during continuous rainfall and the maximum value of the external water pressure acting on the concrete lining wall were reached in the different typical rainfall time. The authors can evaluate further the influence of the rainfall infiltration on stability and safety of the lining wall of TGP ship lock. Results can demonstrate that the concrete lining wall of TGP shiplock chambers has more larger safety, and the drainage system designed in the TGP ship lock slope is in good conditions, the influence of rainfall on the external water pressure will be small especially very strong rainfall continuous rainfall.

Key words: permanent shiplock of Three Gorges Project, high slope, saturated-unsaturated seepage, rain infiltration, exit surface of unsaturated seepage, external water pressure, finite element method
