摘要
为研究桩径对大直径钢管桩水平承载性能的影响,采用ABAQUS数值模拟软件建立大直径钢管桩数值模型,开展数值模拟研究。结果表明:数值模拟所得钢管桩桩顶的水平荷载—位移曲线与实测曲线变化趋势一致,数值模型可靠;单桩水平极限承载力随着桩径的增大而线性增大,当桩径扩大3倍时,相应的水平极限荷载提高1倍;同一深度钢管桩桩身挠度随桩径增大呈逐步减小的趋势。本研究成果可为海上风电场大直径钢管桩施工建设提供参考依据。
In order to study the influence of pile diameter on the horizontal bearing capacity of largediameter steel pipe piles,the numerical simulation software ABAQUS is used to establish the numerical model for the large-diameter steel pipe pile and to carry out numerical simulation study.The results show that:the variation trend of the simulated horizontal load-displacement curve is consistent with that of the measured curve,which confirms that the numerical model is reliable.The horizontal ultimate bearing capacity of the pile increases linearly with the increase of pile diameter.When the pile diameter expands by 3 times,the horizontal ultimate load increases by 1 time correspondingly.With the increase of pile diameter,the deflection of steel pipe pile at the same depth tends to decrease gradually.The study results can provide a reference for the construction of large diameter steel pipe piles in offshore wind power plants.
