Tests on influence of pile-soil-pile interaction

It was pointed out through large scale model tests and a comparison between the measured results and the theoretical solution of elasticity that the theoretical solution of elasticity exaggerated the influence of pile-pile,pile-soil,soil-soil interaction,and it led to the large predicted value of subsidence and overestimated the non-uniformity of the reaction on pile head and non-uniformity of the earth pressure on raft bottom.The difference between the theoretical solution of elasticity and the real value should be estimated in analysis of interaction of superstructure-foundation-soil,and the theorefical solution of elasticity should be revised based on the measured and model test results.
