Based on test data of load sharing between pile and cap of single cap pile foundation below column in the tall building

the properties of load sharing between pile and cap

the reaction forces of pile top and soil between piles are analyzed. Pile and cap can together bear the loads. Pile and soil below cap can respectively share 80% and 20% of total loads. The ratio of loads shared by soil below cap and pile changes largely during early period of the engineering

and gradually becomes stable with the end of main structure. Reaction force of the middle pile is smaller than that of the edge pile and the corner pile. Reaction force distribution of pile top and soil below cap is saddle shape along side cap. The test results of this engineering are useful for design of single cap pile foundation below column in tall building.
