【摘要】 基于煤矿地下巷道开挖后实测位移．提出求解地下巷道各岩层弹性模量的位移反演模型。针对目标函数多极值性、收敛结果与初值及观测误差相关等问题，提出了一种位移反演分析优化算法。数值计算结果表明，本文所提出的数值方法反演的结果是唯一和稳定的。更多还原

【Abstract】 Based on measured displacements of tunnel under ground after excavation, the inverse model of getting modulus of rock elasticity has been set up. The optimization algorithm of inverse analysis from displacements has been suggested accounting of several minimums of the objective function and the results of convergence depending on initial values and measured error. The computational results indicate that inverse results are unique and stable by making use of the method suggested by the paper.更多还原
