Research on Technologies for Driving of Large Assembled Steel Sheet Piles in Caofeidian Coal Terminal

The paper describes the researches on the technologies for driving of large assembled steel sheet piles in Caofeidian Coal Terminal,selection of the final driving method and implementation of the selected method.The results showed that,among the 875 sets of the steel sheet pile assemblies installed for the project,all the H-shape main piles were driven to the design depth,95% of the AZ-shape auxiliary piles were driven to the design depth,and the rest of the piles were within the design deviation.All the piles were driven with good quality.
