摘要
Abstract
The main bridge of the Fourth Nanjing Yangtze River is a three-span continuous steel box girder bridge.A variety of construction conditions, including the deepwater regions in the main channel, the shallow or waterless regions in the side spans at the north and the south side,no cable region in the main tower and the swinging in the ultra-low space at the end of beam are involved in the installation of the steel box girder.In addition,the displacement-limiting cable is set up in the north and south transition pier.All these complex construction conditions contribute to the difficult of the installation of the steel girder.Therefore, this paper focuses on the description of the key technologies of the steel girder installation,which may provide some references to the similar projects to some extent.关键词
