【摘要】 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。更多还原

【Abstract】 Based on the analysis of tunnel convergence in Xieyi Coal Mine, HuainanMine Bureau,the rock mass of coal mine is considered to be a discontinuous in-homogeneous linear viscoelastic medium. By taking account of the inhomogen-eous model and the corresponce principle of linear viscoelasticity, a displacementback analysis by boundary element method is used in the analysis and pre-diction of timedependent stresses and displa cements of tunnel support in softrock.更多还原
