Through analyzing the deflexion mechanism of Double-O-Tube shield, the corresponding rectifying deviation techniques are mapped out. Based on the tunnel section construction of Shanghai rail transit Line 6 between Yun-shan Road station and Jinqiao Road station, the rectifying deviation techniques are analyzed particularly about their advantages and disadvantages, their validity are appraised synthetically. This conclusion can be used as a guidance to the construction of the Double-O-Tube shield tunneling.%为了解决隧道间相互交叉、隧道与其它地下建筑的穿插重叠等问题,采用双圆质构可以在较为狭小的地下空间穿越,节省地下空间,同时也可避免设置联络通道,减小施工风险.通过分析双圆盾构机发生偏转的机理,制订了相应的纠偏措施,并结合上海轨道交通6号线云山路站——金桥路站双圆区间隧道工程实例,详细分析了双圆盾构施工中的纠偏控制措施,并综合评价了各种措施的优缺点及有效性.所得结论对于双圆盾构施工技术的发展具有一定的指导作用.
