根据对淮南矿务局谢一矿巷道移近量观测资料的分析,将煤矿岩体视为不连续非均质线性粘弹性介质。在此基础上考虑非均质线性弹性理论的对应原理,利用边界元法位移反分析法进行分析和预测软岩巷道支护的时变应力和位移。
According to the analysis of the near observation data of the tunnel in Xieyi Mine of Huainan Mining Bureau, the rock mass of coal mine is regarded as discontinuous heterogeneous linear viscoelastic medium. On this basis, the corresponding principle of inhomogeneous linear elasticity theory is considered, and the time-dependent stress and displacement of soft rock roadway support are analyzed and predicted by the boundary element method displacement back analysis.
