Normalized settlement of piled raft in homogeneous clay

摘要

Based on the three-dimensional boundary element method, a practical analysis method for piled raft in clay is presented and validated against the results from the existing numerical simulations and field measurements. A parametric study is performed to investigate the variation of the normalized settlement of the piled raft, including the effects of soil condition, pile dimensions and soil-pile adhesion. Then, a design chart considering the variation of normalized settlement with soil rigidity under different factors of safety is recommended to facilitate the practical engineering design, which is verified against the field and laboratory measurements.
