摘　　要：文章采用ABAQUS软件,结合双线性剪切滑移模型得到了带衬套灌浆锚杆在滑移过程中的内部应力分布及变化过程,根据多因素对锚杆锚固性能的影响程度提出锚杆最大拔出力计算公式。将数值模拟结果和理论计算结果与试验值比对,证明方法合理。基于文章的研究结果给出采用该类锚杆对历史性建筑进行加固时锚杆锚固深度以及钻孔直径取值范围。This paper obtained the stress distribution and evolving of bushing grouted anchors during slip by using ABAQUS combined with bilinear shear slip model.According to the influence of various factors on the anchorage properties of grouted anchor,the formula for calculating the maximum drawing force of anchor is proposed.The results of numerical simulation and theoretical are compared with the test results to verify the rationality of this methods.Based on the research results of this paper,the range of anchorage depth and drill hole diameter are given when this kind of anchor is used for strengthening historic buildings.
