Numerical Simulation of Load Transfer Mechanism of T-Shaped Soil-Cement Deep Mixing Column

Abstract:

T-shaped soil-cement deep mixing column load transfer mechanism is different from the general section column. Basing on the fast Lagrangian finite difference method, we study the load transfer mechanism of T-shaped soil-cement deep mixing column at different load levels, expanding head height and the ratio of upper and lower pile diameter. By the numerical simulation we obtained that the axial force plummeted value of expanding head flange increases with the load and the ratio of upper and lower pile diameter increasing, it will decreases when the height of expanding head increasing.This paper can provide a reference for the design of T-shaped soil-cement deep mixing column.
