Abstract
Model tests of the squeezed and branch pile with or without vertical load are carried out and the horizontal load bearing capacity are studied in this paper. Based on the model test results, the influence of vertical load to squeezed and branch pile horizontal load bearing capacity and the influence of horizontal load to squeezed and branch pile vertical bearing capacity are analyzed with FEM. The analysis results show that the vertical load may increase the lateral bearing capacity of pile, and the horizontal load may decrease the vertical settlement, but horizontal load may increase the horizontal displacement and moment of the pile body and lead to instability and cracking failure. This should be pay more attention in the practical engineering.
