Abstract
The DX pile is a new type of pile which has been adopted to fit the situations of various projects and gets well economic benefits. However, with such advantages, the new developed DX pile was still in the phase of popularization and needs more demonstrated study to provide confidence experience in foundation construction. Based on in-situ practices, this study made comparison of the bearing capacity between DX pile testing method and β method. The results of assessment pointed out that the bearing capacities of DX piles estimated by β method are all less than the actual data obtained from DX pile testing method that came from β method which is more conservative to estimate bearing capacity of the DX pile. Rating at the same size of pile, the DX pile can gain 40% bearing capacity more than the ordinary column piles. With the pile bearing capacity of 470T, this higher bearing capacity of DX pile can reduce the pile diameter ranging from 1.5m to 1m and shorten pile length from 56m to 47.3m; totally save 40% cost approximately.
