The compound foundation,which supports the upper load by both the matrix and the reinforcement,has good engineering characters and great economic advantages. In silty soil,the flexible piles,such as cement mixed piles and crushed stone piles are used for the compound foundation,but the rigid piles,like precast pipe piles,are seldom adopted. Taking the Danjin shiplock as the research object,this paper discusses the idea for revetment soft foundation treatment and foundation selection,and design parameters of compound foundation. Combining with the field test and observation,we analyze the parameter selection and carries out a comparison between the pipe pile compound foundation and the deep mixed pile compound foundation,to serve as reference for the construction and perfection of standards for similar engineering projects.
