To calculate rockmass and surface subsidence by using numeric analysis of rock mechanics, back analysis of displacement is used to study identification and theoretical analysis. 为应用岩石力学数值分析方法进行岩层与地表移动计算，采用位移反分析方法，进行了模型识别和理论分析研究。
The interval parameter perturbation method and the interval parameter back analysis method are studied, and the interval parameter monotony back analysis method is presented. 摘要研究了区间参数摄动法和区间参数优化反分析法，提出了区间参数单调性优化反分析法。
