Abstract:

According to the field experimental results of the reaction of rigid piles with cushion and soil among them for composite foundation of high-rise building, the characteristics of surface pressure of pile and soil among piles, load sharing among piles and soil as well as the settlement of foundation varied with change of superstructure loads are analyzed. Results show that load-bearing capacity of soil can be fully utilized due to installation of the cushion; the gross superstructure load is shared by piles and soil among piles; and the results are compared with that of loading test. The conclusions are useful for further theoretical studies and engineering design.

Key words: high-rise building, rigid pile composite foundation, cushion, load sharing among piles and soil, test in situ
