Research On Bearing Properties Of PC Piles Under Inclined Load

Most of the foundation piles worked under the vertical and horizontal loads in actual. The bearing properties of foundation pile under the horizontal loads haven't arouse some people's value for long time. Especially, sea-crossing bridge, the viaduct, high-rise building and super-tall structures increases rapidly with the tension of city and road traffic development, it makes the foundation pile bearing more horizontal loads except vertical loads. It is most important to make it clear that the bearing property of foundation piles under vertical and horizontal load, and the problem is also need to be urgently solved.Firstly, the existing achievement of research on the bearing properties of foundation pile have been summarized and discussed in the paper after reading the relevant literature both at home and broad. Buckling line differential equation have been established about the foundation piles under the inclined loads, and the displacement and moment of the pile have been calculated, then, discussed the critical problem aimed at PC pile's properties when the above theory used to PC piles.Secondly, some constitutive models in the ABAQUS have been expounded and analyzed, including the Mohr - Coulomb plastic e model, tangential and normal model of the contact interface.Thirdly, A single PC pile's bearing capacity under the vertical load have been simulation analyzed in the ABAQUS, and the result of static load test of the PC piles and simulation analyzed in the ABAQUS have been contrasted. The comparison confirmed that the result of simulation analysis can reflect the actual at some degree, and the moment and displacement of the pile have been provided.Finally, the displacement and moment of the pile under the inclined load with different parameters have been simulated and calculated, and the rule of the displacement and moment of pile have been concluded in the paper.
