得出了水作用下软岩巷道变形机理
许多煤矿不同程度地受到水对巷道围岩水化作用威胁
水对软岩巷道作用引起巷道变形破坏逐渐引起了人们的重视
综述了地下矿井巷道变形破坏的形式和软岩巷道围岩变形的特点
Based on the rock mechanics, elastics mechanics, fluid mechanics and the theory on the coupling interaction of solid and fluid, the dissertation will synthetically illustrate the forms of the tunnel’s deformation, which is under the ground
Meanwhile, it will expound the deformation characteristics of the soft rock tunnel adjacent formation
And the paper analyses the mechanics parameters’ transformation circs of the samples that are in different state ,such as natural condition、hydration for 2 days、4 days and 6 days, and which are from the underground tunnel adjacent formation of the Liyazhuang coal mine
While it will conclude the deformation mechanism of tunnel adjacent formation
And the paper also will present the theory on the coupling interaction of solid and fluid, at last will study the procedure to the deformation and damage of soft rock tunnel in the coal mine called Liyazhuang with the simulation software named FLAC3D,furmore,the paper researches the influence when water acts on the tunnel adjacent formation
