The failure of slopes caused by heavy rains in the typhoon and baiu seasons has taken tolls of lives and done damages all over country [1] [2]. To prevent such disaster, it is necessary to take appropriate measures against slope failure at appropriate spots at appropriate times. Preventive works of such structures as are capable of preventing slope failure have to be chosen, slopes surveyed thoroughly, geology, soil properties, costs of civil engineering works, scenery, and so on taken into account [3]. Slopes requiring such works and their danger levels of failure should be evaluated synthetically, and appropriate spots and times of such works should be determined Accordingly, it is important to estimate the danger levels of slope failure with accuracy of a certain degree, which also helps to minimize the damages by slope failure.
