Nonlinear Analysis of Interaction of Superstructure-Pile-Raft-Soil System in Layered Soil — Part II: Characteristics of Reaction Force on Pile Head and Displacement of Raft

Abstract:

Using the nonlinear analysis method and program of the interaction of superstructure- pile-raft-soil system in layered soil in the state of the previous literature, the reaction force on the pile head and the displacement characteristics of raft of the piled-raft foundation are analysed when the thickness of the raft, the spacing of the piles, the length and the diameter of the pile are changed. Some quantitative data and qualitative conclusions are obtained in this paper.
