Abstract:
Based on the results of pile-foundation-interaction analysis for four high rise buildings, a research on pile groups is made to reveal the load transfer of piles and the applied vertical stress distribution in subsoil Analysis results indicate that pile groups are different from a single pile in load transfer behavior, and that pile group foundations are obviously different to equivalent deep foundations in applied vertical stress distribution in substratum The applied vertical stress is used to calculate the deformation of subsoil The results are in agreement with the deformation measured
