Abstract：In order to study bearing characteristics of squeezed branch piles,through the field static load tests of the squeezed branch pile and the bored pile,comparative analysis of the axial force distribution and the development of pile shaft resistance and pile toe resistance are done.Load transfer mechanism system of the branch pile and the side friction characteristics of the branches in different positions are thorough analyzed.The experiment results show that,the bearing characteristics of branch piles are stable,and its"Q-S"curves of branch piles are slow transformation.The anti-sedimentation deformation characteristics of the squeezed piles are significantly better than that of the bored piles.The side friction of the support plate plays earlier and more adequate than that of the lower branch.The bearing capacity of branch piles is about 36％ higher than that of bored piles.
