摘　　要：采用粘弹性理论的对应原理 ,对轴对称圆巷的粘弹性模型进行了分析 ,从而得出了该模型位移场的理论解。并利用大型通用ANSYS有限元分析软件对轴对称圆巷的粘弹性模型位移场进行了数值模拟分析。在此基础上 。Based on the correspondence principle in viscoelastic theory, the viscoelastic model of axisymmetric round headings has been analyzed, obtaining theoretical results of displacement field in the viscoelastic model. Then, the digital simulation of displacement field in the viscoelastic model of axisymmetric round heading is carried out with ANSYS--a general finite-element analysis software. Then, theoretical and digital simulation results have been compared and analyzed.
