摘　　要：南京大胜关长江大桥4号墩基础施工采用先平台后围堰的施工方案。其水上综合性多功能施工平台集钻孔、钢筋作业及水上混凝土工厂于一体,并利用MIDAS/Civil结构计算软件进行建模计算,节省了临时结构的投入。介绍4号墩综合性施工平台的设计思路与施工方法。The construction scheme for foundation of Pier No. 4 of Dashengguan Changjiang River Bridge in Nanjing is to set up a working platform over the river first and then to construct the cofferdam there. The platform for the construction is designed to have comprehensive purposes, having all functions in one, including those for pile boring construction, reinforcement work and waterborne concrete plant. The platform is also calculated with models established by the structural calculation software MIDAS/Civil and the cost input for the temporary structure like the platform has therefore been saved. In this paper, the design considerations and construction methods for the platform are dealt with.
