抄録

In order to indicate effects of mountain slope distribution in a three-dimensional space, infiltrated water movement in a surface layer is modeled, in the study, by Darcy's law and a continuous equation in a cell which is called a square area determined by a mesh method.<br>To predict site of probable mountain slope failure by evaluating three-dimensional influences of mountain slopes, infiltrated water levels obtained by the model are applied to the multi-planar sliding surface method which was proposed elsewhere. The results show that sites of the most dangerous sliding mass almost appeared at the same sites where failures occurred in the past time.<br>Another predicting method, moreover, is proposed in the present study by using a digital land form model which was also proposed to calculate F values. Infiltrated water levels at each cell are applied to the infinite slope stability analysis method. Potential failure areas are mapped and are classified into various dangerous degrees by the time when the safety factor becomes less than unity under the assumptions that the depth of the surface layer is 1.2m and rainfall, 20mm/hr, continues 50 hours. More hazardous cells are found to appear at the sites where mountain slope failures took place in the past time.
