摘　　要：采用FLAC3D有限差分软件作以及模型试验作为研究手段,结合浙江省台州市某工程实例,对淤泥土层中直孔桩和DX桩的沉降规律进行了对比分析,在相同的荷载作用下,同桩长、同直径的直孔桩和DX桩,DX桩的桩顶竖向沉降要比直孔桩小,DX桩以较小的桩长就能获得与桩长较大的直孔桩一样的沉降,因此在工程中采用DX桩可以节约资源、降低成本。Taken an engineering of Taizhou City in Zhejiang Province as an example, the settlement law of uniform bored pile and DX pile in silt soil are comparatively analyzed by numerical analysis software FLAC3D and model test. When the DX pile has the same length and diameter as uniform bored pile, the vertical settlement of former is smaller than the latter under the same load. In order to get the same settlement, DX pile with less length will do but uniform bored pile should be longer. DX pile applied in engineering can save resources and reduce cost.
