中文摘要：
本文针对地下工程围岩位移反分析问题的目标函数存在多个局部极值的特点，在对模拟退火算法进程中控制参数，即初始温度、每一温度下的状态选取次数和退火策略的确定方法加以改进的基础上．引进有限元分析手段和自适应的思想，建立了基于改进模拟退火算法的位移反分析方法，并开发了相应的分析程序。工程实践分析表明：本文理论计算结果与实测结果吻合良好，该方法较一般模拟退火算法具有明显的优越性。
英文摘要：
According to feature that goal function has more than one local extremum in displacement back analysis for underground engineering, a new means of displacement back analysis for underground engineering has been established through adopting FEM and self-adaptation idea on the basis of the improvement of the determining method of control parameters, such as initial temperature and number of state choice and annealing strategy, moreover, the relevant analytic software is developed. The analysis and comparison on the example of practical engineering indicates that the theoretical results tally well with practical ones, this method is more efficient than general annealing algorithm, and this paper has also perfected the theory about back analysis for underground engineering.
