Abstract

Abstract

Based on the documentation [1],the implicity calculation formula of composite pile-soil stress ratio was simplified by analyzing the deformation character of composite foundation of rigid pile with cap and taking no account of the compression deformation of composite pile,the explicit calculation formula also was deduced for the composite foundation of end bearing pile with cap and friction pile with cap,the settlement calculation formula was obtained according to the mode of soil besides pile cap for composite foundation of rigid pile with cap. At last,by comparing the calculation results with those form documentation [1],it was verified that the feasibility and effectivence of the calculation method.
- composite foundation of rigid pile with cap,
- composite pile-soil stress ratio,
- soil besides composite pile,
- simplification calculation
