Abstract

Abstract

The mechanism of bearing capacity of DX piles are studied by a series of loading tests of full-sacle model DX Piles cast-in-situ. In the paper, bearing capacity comparisons between column piles and DX piles are made, and the load transmission mode of DX pile are studied, which provided the theoretical references for the bearing capacity design of the DX piles in the engineering practice.
