| 摘 要： | 锚杆支护锚固力的传递机理非常复杂,在前人研究的锚固力剪应力指数分布基础上,考虑了围岩体和锚固剂相对刚度对剪应力分布的影响,给出了锚杆锚固力沿杆体长度的计算表达式,并推导出了锚杆锚固段围岩体剪应力沿径向的分布曲线,以期为锚杆支护设计和施工提供更有效的理论指导。

| Abstract: | Transmission mechanism of anchorage force of anchored bolt supporting is very complex.On the basis of shear stress's exponential distribution of anchorage force obtained by former scholar,this paper presented calculation formula of anchorage force along bolt body by considering influence of surrounding rock body and relative stiffness of anchorage agent on shear stress distribution.It also deduced distribution curve of shear stress of surrounding rock at anchorage section along bolt body.The results might p... |
