摘　　要：庄浪应急供水工程1号隧洞设计断面较小、洞线较长,成洞条件差,为选择合理的施工方案,结合1号隧洞的工程地质条件,选定铣挖法为本工程1号隧洞施工的最佳方案,在工期最优的前提下,工程投资较省、质量有保证、施工风险低。同时,还详细的介绍了隧洞工作面安排及支洞布置、支洞设计、隧洞通风以及隧洞施工方法,为该工程及同类型工程隧洞施工提供了方法参考。The design section of 1#Tunnel of Zhuanglang Emergency Water Supply Project is small,the tunnel line is long,and the conditions for tunnel formation are poor.In order to select a reasonable construction plan,combined with the engineering geological conditions of Tunnel 1,the milling and excavation method was chosen as the best plan for the construction of Tunnel 1 in this project.This plan,under the premise of optimal construction period,has lower project investment,guaranteed quality,and lower construction risk.At the same time,it also provides a detailed introduction to the arrangement of tunnel working faces and branch tunnel arrangements,branch tunnel design,tunnel ventilation,and tunnel construction methods,providing method references for the construction of tunnels in this project and similar projects.
