【摘要】 采煤塌陷区隧洞围岩稳定性，既受隧洞自身开挖的影响，又受洞下采煤引起地层移动的影响，是一个极其复杂的问题。通过对隧洞沉降、收敛、裂缝开度及拱架支承压力等的监测，对某隧洞围岩及衬砌稳定性进行了分析和评价。更多还原

【Abstract】 The stability of tunnel in mining-coal induced subsidence area is a complicated problem because of the influence of tunnel excavation and strata displacement induced by mining. The stability of the surrounding rocks and lining of the tunnel is analyzed and evaluated with the tunnel subsidence, convergence, crack opening and supporting force on the steel support measured in site.更多还原
