Abstract:

Accuracy of the slope stability analysis is the key to ensure the stability of deep foundation pit. At present, the common calculation methods used to assume the shape of the sliding surface, and the calculation process is so complex that accuracy of results is decrease. Without any similar assumptions on shape of sliding surface, a minimal potential energy method is used to analyze the stability of deep foundation pit slope. Based on the theoretical analysis of simple homogeneous arbitrary sliding surface slope, it turns out that calculation results attained through the verification of calculation example are relatively close to results from other common methods; and effectiveness of the method is validated. What is more, calculation is simple without iterative process.

Key words: minimal potential energy method, stability, safety factor
