| Abstract: | Zhongxian Yangtze River Bridge is located at Chongqing section,to the upper reach of the Three Gorges Reservoir Area.Construction of main pier base slab is influenced by water accumulation in the Three Gorges Reservoir,the water level is high,the construction time is tight and the construction is difficult.Based on these characteristics,this paper gives a detail introduction to design ideas and design/calculation for large dual-wall steel cofferdam for the deep water bridge piers,and discusses all issues to be paid attention of in design,it plays the role of reference for designing deep water foundation steel cofferdam of similar bridges. |
