摘要
在隧道施工过程中,经常会遇到一些近距离下穿埋深较浅的既有道路工程,如何安全、经济地下穿便成为业界所关注的问题。综合国内外在浅埋地层条件下的几种主要施工方法,从适用条件、结构作用机理以及各方法的特点阐述浅埋隧道下穿道路工程的3种施工技术,并结合已建成的工程实例来说明具体的施工方法。
During construction the tunnels often have to go through some existing shallow-depthed road projects and be constructed under them in short distance,so the safe and economical passing under the road projects becomes a problem of people's concern in this area.By integrating a few principal construction methods under shallow-depthed stratum conditions at home and abroad,this paper describes three construction technologies for shallow-depthed tunnels under road projects in accordance with applicable conditions,functional mechanism of structure and features of various methods,and explains specific construction methods based on completed projects.
