Abstract
Climate change, according to the country to increase locality of slope collapse of heavy disaster, such as increasing the likelihood and prior in order to prevent these disasters, "Slope construction design standards (Ministry of Land, 2011)," is prescribed in the relevant guidelines. In recent years, guidelines Slope Stability Analysis of the existing methods when the rainy season infiltration of rainfall, taking into account have been revised to perform more realistic. In this study, according these trends to the analysis of saturation depth by rainfall intensity and soil conditions. Results as a whole, the larger the saturated hydraulic conductivity and depth of rainfall intensity also showed a tendency to rise in proportion but MH, CL did not occur in the saturation region. Analysis of antecedent rainfall case also reflects an overall increase of depth in the saturated, rainfall in many cases is less than the growth rate was higher in the saturation region.
