摘　　要：针对浅埋圆形隧道部分衬砌渗漏条件下的稳态渗流场,利用保角变换、拉普拉斯方程的级数解以及MATLAB广义矩阵运算等方法得出了隧道衬砌渗漏条件下的渗流场解析解,该解析解与ANSYS有限元软件的模拟结果吻合较好。对解析解进行参数分析,发现隧道半径、隧道埋深以及地表常水头取值等均对解析解的结果有一定的影响。For the steady-state seepage field under partial lining leakage conditions in shallow buried circular tunnels,this paper adopts the method of angle-preserving transformation,the serious solution of the Laplace equation,and general matrix operation functions in MATLAB to get the analytical solution of seepage field under tunnel lining leakage conditions.The analytical solution of this paper agrees well with the simulation results of ANSYS finite element software.Parametric analysis of the analytical solution found that the radius of the tunnel,the burial depth of the tunnel,and the value of the surface normal head all have some influence on the results of the analytical solution.
