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。
Measured Displacement after Excavation of Underground Roadway in Coal Mine. A displacement inversion model is proposed to solve the elastic modulus of rock strata in underground tunnels. Aiming at the problems of the multi-extreme value of the objective function, the convergence of the result and the initial value and the observation error, a new algorithm of displacement inversion analysis is proposed. The numerical results show that the numerical method proposed in this paper is unique and stable.
