A New Method for Inverse Calculation of c and φ on a Slip Surface (Part II)

Inverse Calculation on the Basis of Fellenius Method

Abstract

Our first paper (Part I) has been mainly concerned with the fundamental concept of the newly proposed inverse calculation method of c and φ along a given slip surface. The present paper deals with the embodiment of the concept when the ordinary method of slices (Fellenius Method) is adopted as a means to calculate factors of safety. Results of appling this procedure to some fictitious problems are also presented to demonstrate the availability of the method. As a result, it has been made clear that the proposed method is particularly effective with the utilization of a digital computer.
Applications of this method to real landslides will appear in a succeeding paper.
