| Abstract: | Based on the in situ experimental data,a finite element analysis method was developed to simulate the interaction between soil and the settlement reducing piles.The test data were sorted out and the stress development in the piles and nearby soils was analyzed.Meanwhile,the mechanism of pile-soil interaction and the bearing ratios in piles and soils were analyzed in great details.This approach can be valuable to the engineers in their design practice. |
