摘　　要：为了研究锚杆承载力与其影响因素之间的关系,在一定的假设条件下,对常规拉拔实验物理模型建立了其相应的力学模型,并推导出锚杆的应力应变函数。然后,根据相应的试验结果,深入分析了相应的影响因素:锚固体材料结构参数、注浆体材料力学特性参数对锚杆承载力的影响,在此基础上推导了考虑上述因素的锚杆摩阻力和承载力的计算公式以及其他的一系列结论。In order to study the relationship between the bolt bearing capacity and the impact factors,and under a certain hypothetical condition,the mechanical model corresponding to conventional pull-out experimental physical model is established,and the stress and strain function of bolt is derived.And then,in terms of the corresponding test results,an indepth analysis is made of such impact factors as the effects of bolt material structure parameters and mechanical properties of grouting material parameters upon the bolt bearing capacity,on the basis of which the calculation formulas of bolt friction resistance and bearing capacity in considering the above influencing factors and a series of other conclusions are derived in this paper.
