摘要:By using the finite element software ANSYS and ABAQUS, we established the calculation model of raft foundation anti-floating pile foundation, and studied the mechanical properties of the raft foundation and the influence of raft foundation on the foundation. By comparing the stress and displacement of the anti-floating pile under different pile distance, the influence trend of the different anti-floating pile layout scheme on the mechanical property of the floating slab foundation anti-floating pile is explained, Then the optimal arrangement scheme of anti-floating pile was acquired. Under the action of vertical load, the anti-floating pile effectively reduces the average vertical displacement of the raft, and the raft foundation improves the bearing efficiency of the pile as well as the economic efficiency.
