通过分析水平位移的各个影响因素对位移的作用，指出锚杆位置下移会增加锚杆的拉力并进而加大其配筋，但可以减小桩顶在锚杆张拉锚固后的水平位移变形。

By analyzing the influence on the displacement among every factors , the approach proposes that the downward anchor can increase its tension and reinforcement , but it also can reduce the horizontal displacement of the top end of the pile after the ancher is pre_tensioned .

一般认为锚杆（索）抗滑桩在锚杆（索）拉力、滑坡推力、桩前滑体抗力的作用下绕锚固点（锚拉力作用点）保持力矩平衡，锚固点为一铰支点。

It is a balance system that the anti-slide pile is exerted by three kinds of force , they are the tensile force of anchor , the thrust of sliding mass , the resistance of soil and rock .

煤矿井下可回收锚杆一般用于煤层巷道，由于锚杆钻孔的变形和塌孔等原因，用普通套筒扳手拆卸锚杆时，因不能给锚杆提供轴向拉力，很难将锚杆拆卸拔出。

It is difficult to pull out the bolt with ordinary socket wrench that can not provide axial tension because of the bolt drilling hole deformation and the collapse of holes .
