Analysis of the Response of Pile Groups Considering Pile–Cap–Soil Interaction in Layered Soil

Abstract

The shear displacement method was used to simulate the response of pile groups considering pile-cap-soil interaction in layered soil. The pile cap was modeled using the finite element method with 16-node degenerate elements and the pile-pile interaction was assumed to be in a linear elastic state. The effect of the reinforcement effect between plies on the response of pile groups was considered. The obtained calculation results were compared with values estimated in finite element and field tests, and the feasibility of the proposed model for the analysis of a pile group and piled raft foundation was verified.
