管缝式锚杆的轴向受力特征

详细讨论了管缝式锚杆的轴向受力特征，指出了锚杆轴向力，剪应力、轴向应力及轴向位移均呈指数分布，直至临界滑移状态的均匀分布，为了使理论模型更接近实际，提出了以现场拉拔试验确定模型参数的方法。

Axial Stress and Displacement Distribution of Split-Set Bolt

Load/stress conditions and deformation distributions of a split-set bolt are discussed. Based on a conceptual model,all its axial load,shear stress,axial stress and displacement are shown an exponential distribution which keeps uniform till critical slipping. To find more applications with the model,a correction factor is determined through pull-out test in site.
