摘　　要：文章根据库伦强度理论,综合考虑合肥地区膨胀土物理力学性质、锚杆埋置于土层的深度以及地下水的影响,提出对抗浮锚杆极限粘结强度进行估算,并与实际工程锚杆试验案例做对比,估算结果较试验结果略小,可满足工程应用。According to the Coulomb strength theory,the ultimate bond strength of anti-floating anchor is estimated,which are comprehensively considered the physical and mechanical properties of expansive soil in Hefei area,the depth of anchor embedded in soil layer and the influence of groundwater.Compared with the test results,the estimated results are slightly smaller than the test results,which can meet the engineering application.
