摘　　要：随着社会的快速发展,城市中各种道路的改造拓宽已满足不了繁重的交通负载,特别是在主要的交通路口拥堵现象更是严重。主干道下穿隧道设计方案成了一种不错的选择,而在拥堵的城市道路进行隧道施工,可适宜采用盖挖法施工,以有效保证施工安全以及交通顺畅。以扬州城市南部快速通道扬子江路隧道为例,分析解决复杂条件下的隧道施工技术——盖挖法施工技术。With the rapid development of society,the transformation and widening of various roads in the city can not meet the heavy traffic load,especially the congestion phenomenon at the main traffic intersections.The design scheme of crossing the tunnel under the main road has become a good choice,and the tunnel construction on the congested urban roads is suitable for cover excavation construction to effectively ensure the construction safety and smooth traffic.This paper takes the Yangtze River Road tunnel as an example to analyze and solve the tunnel construction technology-cover excavation construction technology under complex conditions.
