Discussion on applicable conditions of composite pile foundation in soft clay

The root of composite pile foundation is pile-soil interaction,while deformation coordination between piles and soil is the precondition of the pile-soil interaction. Larger difference of bearing stiffness of piles and soil is existent usually,so certain measures must be taken to ensure deformation coordination. This paper discussed on the application condition of composite pile foundation based on mechanism of pile-soil interaction,and concluded that when the rate of bearing capacity of natural...
