| Abstract: | 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. |
