摘　　要：为验证Abaqus粘结接触模型在拉力型锚杆抗拔试验数值模拟中的适用性,对珠三角某水利工程中的基础抗浮锚杆进行数值模拟,将计算结果与实测数据相对比,结果表明:模型计算得到的荷载-位移曲线与实测数据接近,锚杆在验收试验最大荷载作用下未发生破坏。锚杆在验收试验最大荷载作用下,轴力随着深度的增加而逐渐减小,不是均匀分布;超过一定深度后,锚杆轴力为0。To verify the applicability of cohesive behavior in Abaqus on the numerical simulation of the pull-out test of anchor,a case study of anti-floating anchor in a civil engineering at Pearl River delta was carried out.The simulation results were compared with the measured data in the field,and it revealed that the load-displacement curves obtained by simulation were closed to that in the field.The anchor would not be failed under the maximum load of the acceptance test,and the axial force was decreased with the depth,which was obviously not uniform.The axial force was decreased to zero as the depth excess one certain value.
