| Abstract: | Using analytical method, the calculated formula of the safety factor is established in the case of a circular failure surface for foundation dig. Using the conditions that a function takes on the minimum value, two alternating algebraic equations are given to determine the most critical slip surface for foundation dig,and the most critical depth of slip surfaces and the minimum safety factors are obtained |
