| Abstract: | The static drilling rooted drainage pile is a new technology, and its bearing characteristics need to be studied in depth. Combined with numerical simulation, the finite element analysis of static drilling and rooted drainage piles is carried out. Firstly, the model test of static drilling and rooted drainage piles is simulated, and the reliability of the numerical model is verified by the comparison between the simulation and the experiment results. On this basis, modeling is carried out according to the engineering scenario to study the bearing characteristics of drainage piles, focusing on the effect of vacuum negative pressure pumping drainage time on the bearing performance of pile foundation. The research results can provide reference for the promotion and application of static drilling root drainage piles. |
