摘要：

Every year, numerous numbers of slope failures are induced by heavy rainfall with the influence of monsoon especially in developing countries in Asia. The finite element method has been often used to analyze the mechanisms of slope failure under rainfall. Usually a high-spec calculator and a long period of calculation time are inevitably required to carry out such rigorous simulations. In this study, however, a simple prediction method for groundwater rising in natural slopes of the ground comparatively shallow depth is developed based on the parametric studies with the finite element method under the assumption of semi-infinite homogeneous slope, and in the future such method will be adopted more for the above system since the calculation cost is expected to be much lower.
