1、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.───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。
2、Underground excavation leads to surface subsidence. Once the surface deformation value exceeds a certain limit, the railway in surface subsidence area will be seriously damaged.───地下开挖工程导致地表沉陷,一旦地表变形值超过一定界限时,地表沉陷区内的铁路就会受到严重PoHuai。
3、In underground structure, excavation method has a great impact on land subsidence and structure stability.───在地下结构中,开挖方式对地表沉降和结构稳定影响很大。
