摘要
为了充分了解巷道围岩与支护结构之间的相互作用关系,在基于弹塑性分析的前提下,将收敛-约束法应用于巷道围岩-支护相互作用分析中,并结合FLAC3D数值模拟软件,分别分析不同巷道支护前位移和不同支护结构刚度对巷道变形的影响。
In order to fully understand the interaction relationship between surrounding rock and Supporting structure,based on the elastic-plastic,convergence confinement method was applied to analyze interaction of surrounding rock and support,combining with FLAC^3D numerical simulation software ,analyzes the different displacement of roadway before supporting and supporting structure stiffness influence on deformation of roadway.
