摘要
武汉地铁7号线工程首创世界越江超大盾构隧道和"公铁合建"地下四层综合交通枢纽车站。该工程技术创新包括过街通道下穿市政隧道最大断面矩形顶管成套技术,华中地区体量最大、技术最先进的野芷湖车辆段,首次在城市轨道交通领域实现超大跨度超大重量桥梁转体施工,建造武汉地铁复杂地质环境条件下最大断面暗挖隧道,越江公路隧道风塔与超高层建筑核心筒合建。所取得的一系列工程创新和技术突破产生良好的社会影响和经济效益,代表城市轨道交通发展的世界先进水平,具有显著的示范效应和开拓意义。
Wuhan metro line 7 project has been the first to create the super large shield tunnel across the river and the underground four-story integrated transport hub station of Highway-Rail Construction.The technical innovation of the project includes:the complete set of rectangular pipe jacking technology with the largest profile of municipal tunnel under the crossing passage,the largest scale and the most advanced technology of Yezhi Lake depot in Central China,for the first time,the construction of the super long-span and super heavy bridge in the urban rail transit,and the construction of the largest cross-section underground tunnel under the complex geological environment of Wuhan metro.The wind tower of the cross-river highway tunnel is built in combination with the core tube of super high-rise building.A series of engineering innovation and technological breakthroughs have generated good social and economic benefits,representing the advanced level of urban rail transit development,which has significant exemplary effect and pioneering significance.
