重庆渝中连接隧道位于重庆市最复杂的城区，隧道沿线高楼林立、管网密集，上跨轨道交通6号线，下穿轨道交通1号线小什字车站。该隧道设计、施工、管理难度极大，施工控制性节点环节多。选取有代表性的施工控制性节点———侧穿华夏银行段作为研究对象，通过分析隧道在不同开挖顺序对中隔墙偏移情况的影响，确认该隧道先开挖右洞后再开挖左洞是较优的开挖方式。此外，还对建筑偏压情况下隧道的合理开挖的机理进行分析，研究结果可为复杂城区类似隧道的设计、施工提供借鉴。

Chongqing Yuzhong Connecting Tunnel is located in the most complicated urban area of Chongqing, the tunnel line is full of high-rise buildings and dense pipe networks, overpasses rail traffic line 6 and underpasses Xiaoshizi Railway Station of rail traffic line 1. Design, construction and management of this tunnel face extreme difficulties, and there are multiple control nodes in construction. By selecting the representative control node in construction-side-through Huaxie Bank section as the object of research, this paper confirms an optimal excavation method of the tunnel in which the right hole is excavated before the left hole via analysis for influence on different excavation sequences on deviation of mid-partition. In addition, the paper analyzes the mechanism of reasonable excavation of the tunnel under the building bias, and the results of research can provide a reference for design and construction of similar tunnels in complicated urban area.
