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