... determination of the limiting failure surface. While the limiting depth zl = 3.62 m occurs at point B in Fig. 2, the depth of the tension zone zt = 1.92 m at point C. The maximum height hd of the slope equals 16.62 m at point D. Thus, it is reasonable to assume that the fator of safety is equal to one...
