With the reduction of high-quality coastline resources,the construction of new wharves faces much more problems such as harmful unfavorable geologiccal conditions and complicated wind and wave conditions.So,the wharf’s piles should be much longer and have better endurance capacity mechanical performance,which means the design of new wharfs have higher demands than the traditional designcalls for higher requirements of wharf design.In this case,the combination pile of steel and concrete,as a new type of wharf pile,is employed as the foundation of crane’s block,As a new type of future candidate pile,the pile combined of steel and concrete is which has a better performance and lower cost comparing with the the previous additional steel pipe pile,concrete pipe pile and the PHC pile with higher performance and low in cost,which was employed in the foundation of crane’s block in this project.Additionally,the this place of geologic condition of the project site is very poor,where the soft silt-layer is thick,and which makes the length-diameter ratio of some piles’s proportion of length to diameter so big.To guarantee the safe construction of the super long pile,we carry out an in-depth analysis on the pile’s lifting,transportion and pilingthe process of lifting,transporting and piling is deeply analyzed.
