To solve the problem of construction on the bank slope in the late construction stage of an inland framed wharf on island platform,BIM technology is used to simulate construction of filling,excavation and stone throwing in the project of the comprehensive terminal in Hexi operation area of Zhangshu port area in Yichun Port,and an implementation plan is proposed that contains island excavation by partitions,collaborative operation between excavators and dredgers,stone throwing with self-dumping and string bag.Engineering practice shows that compared with the steel platform,the construction by island platform saves the total construction period by about 40 days and the construction costs by about 7 million yuan,in which the new construction technique for complex spatial bank slope can shorten the construction period by 10 days.The research results can provide reference for similar projects.
