Construction Technologies of Super-Long Pile Foundation in Hangzhou Bay Bridge
Due to the complicated construction condition, i.e. formidable natural conditions and complicated geological conditions and the large scale of bay bridges, the design and construction of Hangzhou bay bridge have inevitably encountered numerous obstacles, among which the construction of large scale pile foundation is a crucial one. In this paper, the key technology and countermeasures of construction of large scale pile foundation in rich shallow-buried gas in offshore zone of the south shore beach area are introduced. Deformation of the steel casing pipe and countermeasures project was studied in the pile construction of south and north channels bridge piers. In addition, such technologies as installation of cathode protection, large-sized pile-sinking barge performance and pile-sinking hammer model, are studied in steel-pipe pile foundation construction of water area. The results will serve as a theoretical foundation and guidance for successful construction, operation safety and sufficient durability of Hangzhou bay bridge, and also as a reference for design and construction of other bay bridges in China.
