摘　　要：通过大型三维数值模拟计算及相关分析,确定某浅埋、土质隧道下穿环城高速公路曲线段施工方法及采取的主要措施;结合现场监控量测数据,分析隧道施工相关参数与高速公路变形之间的相互关系,给出合理的仰拱封闭成环距离相关建议。By means of large-scale three-dimensional numerical simulation and analysis, the suitable construction methods and measures are determined for a large cross-section shallowly-buried soil texture tunnel beneath a curved section of a ring expressway in this paper. Also, this paper, in combination with on-site monitoring measurement data, analyzes the relationship between the relevant tunnel construction parameters and the expressway deformation, and gives reasonable suggestion about the proper distance for the enclosing of the invert arch.
