Abstract The buoyancy of groundwater can reduce the foundation bearing capacity and cause the metro tunnels to float as a whole, which threatens the safety of
structures seriously. Therefore, uplift piles are set up to improve the structural stability. In this paper, FLAC3D software is used to establish the calculation models
of pile foundation. The bearing failure process of uplift piles was simulated to
study the influencing factors on single pile load bearing capacity as well as the
cooperative work laws of pile groups. The load-displacement curves of pile top
under different length-diameter ratios, pile-soil interface characteristics and pile
types are… More >
