Based on the mechanism analysis

a new simplified analytical method for the pile-soil-cap interaction is proposed. According to the static loading test results

the single pile settlement at a given loading can be determined. Assuming the soil deformation between the cap and pile toe is equal to the single pile settlement

the cap shared loading can be determined conveniently at a given single pile loading. The foundation settlement is produced by the soil deformation between the cap and pile toe and by the soil compression caused by the loading of piles and cap below the pile toe. An example of the proposed method is presented; and the comparison with field measurements shows that the proposed method is satisfactory.
