Abstract

Based on the limit equilibrium theory and the failure model of the soil nailing structure, used the circular slice method and the geometric relationship of circular sliding surface with the center of the circle to derive the stability coefficient formula. The most dangerous slip surface was searched by genetic algorithm. To establish the reliability analysis function through the stability coefficient formula. Finally, the reliability calculation of engineering examples, compared the results with the Monte Carlo method, the reliability analysis method was reasonable and valid.
