Experiment Study of the Uplift Mechanism of Disk Piles

Abstract:

Based on the analysis of the uplift mechanism theory of the disk piles, a model test device was designed to study the uplift bearing capacity and deformation behavior of the disk piles and to compare with the equivalent diameter piles. Uplift loading tests were carried out on the equivalent diameter pile, the single-disk pile and the double- disk pile respectively. Through the test, it was proved that the uplift bearing capacity of the disk piles was much better than the equivalent diameter pile. The bearing capacity of the single-disk piles was better than the double-disk piles in the test. This was mainly related to the embedded depth of the upper disk was not enough and the specific failure mode. So, a reasonable design was necessary.
