摘要

充分地考虑土钉支护的特殊性，建立了一个比较精确的基于一般破裂面的土钉支护稳定性分析方法。对土钉支护内部稳定分析和外部稳定分析分别建立其优化数值分析模型；然后导入模拟退火算法和随机投点法，结合两者的特长建立了一种可有效求解该模型的耦合算法，并编制了相应的计算程序；通过工程实例证明了基于一般破裂面的土钉支护稳定性分析方法的有效性，并得出了若干对土钉支护稳定分析具有参考意义的结论。

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.
