拟建的沪崇苏隧道是联系上海、崇明岛和江苏的大直径、长距离、高水头越江隧道,其工程规模大,技术难度高,施工中将会遇到各类可能引发严重地质灾害的不良地质条件,能否通过施工措施解决这些技术难题,将成为沪崇苏隧道安全、可行的关键所在。本文根据国内外越江隧道的施工经验,主要就沪崇苏隧道可能遇到的不良地质情况进行分析,提出合理的施工技术措施,为今后隧道建设提供有益的参考。
The proposed Shanghai-Chongsu Tunnel is a large-diameter, long-distance and high-head cross-river tunnel linking Shanghai, Chongming Island and Jiangsu. The project is large in scale and highly technical and will encounter various types of geological hazards that may cause serious geological disasters Bad geological conditions, whether through construction measures to solve these technical problems, will become the tunnel of Shanghai and Chong Su safe and feasible key. Based on the construction experience of tunnels at home and abroad, this paper mainly analyzes the possible adverse geological conditions of Shanghai-Hongshuang tunnel and puts forward reasonable technical measures for construction so as to provide useful reference for tunnel construction in the future.
