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.
