中文摘要：

首先根据锚固体与围岩体界面遵循莫尔-库仑屈服准则建立了注浆岩石锚杆的剪应力的分布函数。在此基础上,根据围岩体与注浆岩石锚杆相互作用机理,建立了围岩体中注浆岩石锚杆的实际受力下的剪应力的分布函数和轴向载荷的分布函数。同时,根据中性点的概念,建立了中性点的计算公式。最后,详细分析了影响锚杆实际受力的各种因素对其受力的影响,为分析其锚固机理提供了一定的理论基础。

英文摘要：

The shear stress distribution function of grouted rock bolt is set up based on the interface between bolt and wallrock mass and following the Coulomb-Mohr yield criterion. On this basis, the distribution functions of the shear stress and axial load of the grouted rock bolt in wallrock under the actual stress are set up based on the mechanism of interaction between wallrock mass and grouted rock bolt. Meanwhile, a computing formula of neutral point is set up according to the concept of neutral point. The effects of various factors on the actual stress of bolt are analyzed in detail, providing a certain theoretical basis for analyzing its reinforcement mechanism.
