A Study on Three-Dimensional Slope Stability Analysis

Past research has concentrated on refining two-dimensional analysis techniques. Rather extensive comparisons of various two-dimensional methods have been made. This paper described a general threee-dimensional method of analysis by which any geometrical condition and any c, phi soil can be analyzed. The results are as follows; 1.Factors of safety computed for 3-dimensional geometry differ considerably from ordinary 2-dimensional factors of safety. 2.3-dimensional factors of safety are generally much higher than 2-dimensional factors of safety. However, situations appear to exist where the 3-dimensional factor of safety can be lower than the 2-dimensional factor of safety. 3.Teh F3/F2 ration appears to be quite sensitive to c, phi and to the slope.
