| Abstract: | This article describes the features of DX piles and summarized the advantages and disadvantages of these piles from the application of them to the pile foundation of highway bridges in Hebei Province.At the same time,it has been proven from the test results of piles for three highway bridges that the ultimate bearing capacity of vertical compression for single pile is significantly higher than that of the same diameter and length of straight bored piles,and increases greatly the capacity of pile. |
