Analysis on Infulence of Pile Spacing Acting on Bearing Capacity of Pile and Soil under Pile Cap Together

In this paper, the caculating model of pile foundation accounting for bearing capacity of soil under pile cap is established. The influnces of pile spacing on load-sharing ratio, settlement and pile top force has been analyed. The result shows that load-share ratio of soil under pile cap and the settlement of pile foundation increase with the pile spacing; and the force of each pile tends to uniform with the pile spacing increasing gradually.
