摘　　要：桥梁下部结构的设计对结构整体变形和承载能力影响较大。文章通过数值模拟方法研究了大直径管桩和实心桩的竖向承载性能。结果表明:在用料相近的情况下,大直径管桩与实心桩的竖向承载性能较为接近,大直径桩拥有更大的侧摩阻力,在整体性能上优于实心桩。The design of bridge substructure has a significant impact on the overall deformation and bearing capacity of the structure.The vertical bearing performance of large-diameter pipe piles and solid piles is studied through the numerical simulation method.The results show that,with similar materials used,the vertical bearing performance of large-diameter pipe piles and solid piles is relatively close,and large-diameter piles have greater lateral friction resistance,which is superior to solid piles in overall performance.
