采用改进型拉拔方式对锚杆进行拉拔试验，从而研究砂浆强度和锚固深度对锚杆承载力的影响，通过在锚杆表面粘贴应变片，得到拉拔过程锚杆—砂浆截面剪应力沿锚杆全长分布规律，根据现场锚杆拉拔过程的破坏形式，分析对应破坏机理。

In order to study the influence of mortar strength and anchorage length on the bearing capacity of anchor,the modified methods were adopted for anchor pullout test. Strain gauges were pasted on the anchor surface and the shear stress distributions along anchor full-length were obtained,the corresponding failure mechanism was analyzed according to the bolt failure modes.
