A parametric analysis of slope failure with numerical method was presented in this paper. Before the
parametric simulation, a procedure of analysis was examined. In consequence, the identifying method of
parameters except the aimed parameter was shown and cumulative rainfall was selected as the evaluation
value in the analysis. With this method, sensitivity evaluations of some parameters are invesitigated. As a
result, parameters which accelerated landslide are, steeper, longer, shallower soil slope and convex slope
figure. And the parameters on physical and mechanical properties, smaller hydraulic conductivity, smaller
cohesion and internal firiction angle accelerate landslide. In addition, parametric values, which concerned
with the seepage and made the initial wet condition of slope, promoted the failure.
