Summarize on the optimum design method of composite foundation

Ding Jun

Abstract

Some conclusions of researching pile-soil interaction are summarized.By studying the interaction of the pile-soil deformation and the stress ratio redressal relation.The internal relationship of pile-soil stress ratio and pile-soil mould ratio is obtained.And then a new optimum design method of composite foundation is put forward.The generation of cushion technique is introduced,form two aspects:coordination between pile and soil and load distribution.In the end,the formula of the bearing capacity of composite foundation for calculating is given.
