Numerical simulation study on the bearing performance of large diameter pipe piles based on FLAC^(3D)

为研究不同壁厚的大直径管桩的承载性能,应用FLAC^(3D)软件进行数值建模,对于其竖向承载性能与横向承载性能开展数值模拟和研究分析。结果表明:单桩承载力极限值均集中于79000~82000 kN,桩身壁厚的大小会对桩体的承载性有直接影响。

In order to study the bearing performance of large diameter pipe piles with different wall thickness,numerical modeling is applied to FLAC^(3D)software,and numerical simulation and research analysis are carried out for their vertical and transverse bearing performance.The results show that the ultimate values of the monopile bearing capacity are concentrated in the range of 79000~82000 kN,and the size of the pile wall thickness will have a direct influence on the bearing performance of the pile.
