Three-dimensional Numerical Simulation for Construction Method of Single-arch Four-lane Road Tunnel

单拱四车道公路隧道施工方法的三维数值研究

A general program using APDL ( ANSYS parametric design language), which is applicable to arbitrary lining sections of the three-centered circular arch with different surrounding rock pressure distributions, was developed for the calculation of the tunnel inner forces and eccentricities.

利用ANSYS的参数化高级设计语言，编制了适合任意三心圆拱衬砌断面和不同围岩压力分布形式的隧道衬砌内力和偏心距的通用计算程序。
