Description
The condition of slope failure occurrence depend not only on rainfall but on the states of slope. The discussions from both sides of rainfall and slope may be neccessary to elucidate the condition of slope failure.<BR>In this paper, an equation of safety factor including the degree of saturation as a parameter, in addi tion to the another parameters such as slope inclination, depth of soil layer, cohesion of soil, void ratio, etc. is introduced to estimate the volume of water in the soil layer at the time of occurrence of slope failure.<BR>The critical volume of rainfall which induce the slope failure is converted from the volume of water in the soil layer which is calculated by using the equation of the safety factor<BR>.The time to slope failure can be forecasted by knowing the time when the accumulated volume of precipitation reaches the critical volume estimated by the presented method in this paper.
