This paper discusses the advantages of the wharf construction in the EPC mode.Combining with a bulk cargo dock in Suzhou in EPC mode,this paper optimizes the pile arrangement of high-pile wharf by increasing the pile caps to set lengthways vertical piles,increasing pile slope to reduce the amount of raked piles,setting the angle and position of lengthways oblique piles flexibly,etc.The optimized layout of pile foundation not only makes the construction easier,but also improves the piling efficiency and saves the engineering investment.
