对DX桩进行了现场竖向抗压静载试验，并与后压浆直孔灌注桩进行了比较。结果表明，DX桩和后压浆钻孔灌注桩都可以提高桩的承载力和控制桩的沉降，4根试验桩的试验效果相差不大，但DX桩能以桩径小、桩长短满足大承载力的桩基，达到极限承载力时，混凝土的单方承载力是后压浆钻孔灌注桩的1.5倍，可以减少工程材料，降低工程造价；且DX桩施工工艺更简单，能加快施工进度。

The in-situ vertical resisting compression static test of DX pile is made and it is compared with post-grouting bored pile. The results indicate that DX pile and post-grouting bored pile can enhance capacity and control settlement effectively;effect of four test piles is not quite different, but the DX pile is of smaller diameter and shorter length which can meet large capacity; its concrete bearing capacity of per cubic meter is 1.5 times larger than that of post-grouting bored pile; DX pile can reduce engineering materials to lower project cost and speed up the construction progress.
