Abstract

In the design of composite foundation,rigid pile spacing is equal 3～5 times the pile diameter,pile length and pile diameter based on the design of composite foundation bearing capacity and settlement target identified.comparing the composite foundation bearing capacity and settlement calculation level,the rigid pile composite foundation settlement level is particularly important,and deformation control design is more reasonable.In this paper,based on the existing theory and the theory considering the pile cap effect of composite foundation,used the rigid pile load test results and multi-pile composite foundation large load test results,to improve existing settlement calculation method of rigid pile composite foundation,reached a preliminary conclusion for design reference.
