| 摘 要： | 本文针对目前巷道加固中普遍应用的锚注支护结构在理论研究方面的不足，从突变理论出发建立了锚注支护体的突变理论模型，得到了锚注体破坏的力学判椐和点（N，q）在控制空间的运动途径对岩体稳定性的影响，并通过破坏力学判椐得到关键承载岩体由一层锚注岩体构成时的最小厚度，为实际计算和应用提供了理论依据。

| Abstract: | in this paper,considering incompleteness in theoretic study about bolt-grouting structure applied universally in roadway reinforcement at present,model of mutation theory about bolt-grouting body is established according to mutation theory,obtain mechanical determinant about the failure of bolt-grouting body and the influence on stability of rock mass in movement path of point(N,q)in controlling space.At the same time,the minimum thickness of key bearing rock mass making up of only a layer of bolt-grouting rock mass was obtained according to failure mechanical determinant.This movided theoretical bases for practical calculations and application. |
