The Research of Raft Foundation Anti-floating Piles’ Performance and its Impact on the Raft Foundation

By Qiuyun Hong, Bin Yan and Tingyu Ma


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
