Abstract The siphonic drainage in slope is a type of new technology in the stage of explorative application. Based on generalized Darcy?s law and the basic principle of seepage，combining the“pipe to represent hole”method and analytical element method，a numerical simulation method for siphonic drainage system is proposed. In order to simulate the process of siphonic drainage，we give the drainage hole a equivalent permeability coefficient according to the equivalence principle of flow and head. And the hydraulic boundary conditions according to the principle of the siphonic drainage are determined. As an example，a three-dimensional finite element seepage model with a single drainage hole is established. The groundwater line and the change of seepage field distribution in the slope before and after siphonic drainage are calculated，which reveal the influence law of siphonic drainage on the groundwater seepage field. In conditions of constant of drainage hole diameter and length，effects of the change of position of drainage hole on drainage have been simulated. The results indicate that the selection of siphonic hole position in slope has important influence on drainage.
