Title: Three-dimensional Numerical Analysis of Stress and Deformation of Soft Soil-pile group-pile Cap System under Coal Pile Load
Abstract: In order to study the stress and deformation characteristics of adjacent pile cap system under the action of coal pile load in soft soil site, taking a large coal storage field in Malaysia as the specific engineering background, based on the large finite element numerical computing platform ABAQUS, the three-dimensional nonlinear numerical model of pile foundation and soft soil site under the action of pile coal load is established to consider the spatial stiffness effect, the stress deformation analysis and safety evaluation of pile group foundation pile foundation for a given site are carried out. It can provide guidance and reference for the design and practice of related engineering.
