Abstract

Abstract: The influence of karst factors on the stress and settlement of the raft foundation is presented through a three dimensional numerical analysis by using ANSYS software. The analysis considers the interactions between the superstructures and foundations. Different karst cavity depth, radius, shape, stiffness, Poisson's ratio and thickness are investigated and their influences on the stress and settlement distribution in the raft foundation are discussed.

Key words: Karst Cavities, Superstructure Foundation Interaction, Raft Foundations, Finite Element Analysis
