以被动加载型锚杆为研究对象，建立了关于锚杆和土壤的力学模型，研究了土体滑移对锚杆造成的影响。用ANSYS对选取的锚杆和足够大区域土体进行分析，采用弹簧单元Spring?damper14来模拟外界土体和该区域之间的联系，并选取Drucker?Prager材料模型来描述土体的本构关系。研究结果表明，当锚杆受到沿锚杆垂线方向移动的土体作用时，位移变形是不均匀的，最大位移变形处在杆的端部；应力分布沿杆长方向也是不均匀的，锚杆在靠近端部位置剪应力达到最大值。

This paper aimed to study passive loading anchor, mechanical models of anchors and soil were established. The influence of soil slip on anchors was studied. ANSYS software was selected to analyze anchors and large enough area soil, Spring?damper14 element was used to simulate connections between outside soil and this area. Drucker?Prager material model was used to describe constitutive relation of soil. The results show that displacements are uneven when anchors are subject to effect of soil movement along vertical direction of anchors. The maximum of displacement locates at the end of anchors. Stress distribution along the direction of anchors is also uneven. The maximum of shearing stress locates near the end.
