中文摘要：

为了分析巷道围岩承载结构与支护的相互作用，建立了圆形巷道围岩内、外承载结构弹塑性分析力学模型，应用广义Hoek—Brown破坏准则和弹塑性基本理论，得到了塑性区半径和围岩承载结构相关参数的表达式．通过实例分析了巷道围岩承载结构与围岩稳定的关系，以及支护力对巷道围岩承载结构相关参数的影响．结果表明：外承载结构位置、宽度以及塑性承载结构宽度与巷道围岩变形量及塑性区范围密切相关；随支护力增大，巷道围岩承载结构越靠近巷道周边．

英文摘要：

In order to analyze the interaction relations of bearing structure and supporting of roadway surrounding rock, the elastic - plastic mechanics analysis model of inner - outer bearing structure of circular roadway surrounding rock is established, by ~means of applying the generalized Hock - Brown failure criterion and the basic theory of elastic - plastic. The expressions of the radius of plastic zone and the related parameters of surrounding rock bearing structure are obtained. Relationship between the bearing structure and the stability of surrounding rock of roadway surrounding rock, and the influence of supporting pressure on the bearing structural parameters of surrounding rock of roadway are analyzed by one instance. Results show that the position and width of outer bearing structure and the width of the plastic bearing of surrounding rock of roadway and the range of plastic bearing structure of roadway surrounding rock approaches structure, have greater influence on the deformation zone. With the increase of supporting pressure, the the perimeter.
