Abstract: Fully considering the speciality of soil nailing, a rather precise method of stability analysis of soil nailing based on general fracture surface is presented. The optimization numerical models for inner and exterior stability analysis are firstly proposed, and then a coupling algorithm of simulated annealing algorithm and random disposal-method of points is introduced for solving the model. Such a coupling algorithm is mainly based on the combination of merits of two kinds of optimization method. Several practical examples have been used to testify the efficiency and ability of the proposed method. Not only the effectiveness of it is demonstrated, but also several important conclusions being able to be referred in the stability analysis of soil nailing are simultaneously drawn.

Key words: soil nailing, general fracture surface, stability analysis, simulated annealing algorithm, random disposal-method of points, coupling algorithm
