忠武输气管道山岭隧道研究

Pipeline Tunnel Design on Zhongxian-Wuhan Gas Transmission Pipeline Project

以忠武管道工程山岭隧道为例,总结了管道用山岭隧道的特点,说明管道用隧道的选用应根据管道工程的功能要求,结合现场地形地质条件和各线路比选方案,经经济技术综合比选确定。管道用隧道轴线的布置既要考虑管道敷设的要求,又要考虑隧道施工的可行性和安全性要求。

Taking the tunnel of Zhongxian-Wuhan Gas Transmission Pipeline Project for example, authors summary the design characteristics of the pipeline tunnel,and point out that the design program's determination on the pipeline tunnel should take project's function and demand into account based on geological conditions and different pipeline route comparison scenarios,especially a technical and economic evaluation. Authors point out that the design in laying-out tunnel's pipeline axial line should meet the requirements of pipeline laying and feasibility and safety in tunnel construction. Design cases for different pipeline tunnels are given in the paper.
