Swedish Circle Method Swedish circle method for analyzing the slope stability: This method was first introduced by Fellenius (1926) for analysis of slope stability of C-φ soil. In this method, the soil mass above the assumed slip circle is divided into a number of vertical slices of equal width. The forces between the slices are …
