铁路隧道下穿高速公路设计方案分析

On analysis of design scheme for railway tunnel through expressways

以某隧道下穿长安高速公路的工程实例为基础,探讨了施工方法、相关荷载的确定,同时以数值计算的方法确定结构截面及配筋,从而为后续类似工程的设计提供借鉴。

Based on the engineering example of some tunnel through Chang＇ an Expressway, the study explores the identification for the construction method and relative loading capacity, and identifies the structural section and reinforcement by adopting the numeric calculation methods, so as to provide the reference for the design of following similar projects.
