Numerical Simulation of the Construction Process of Long Spiral CFG Piles

Advances in Civil Engineering, 2021
A numerical model for the construction process of long spiral CFG piles is established based on the coupled Eulerian–Lagrangian method. The construction process is divided into drilling process and concrete pouring process for modeling. The influence of long spiral CFG piles construction on saturated sand foundation is studied, and dynamic responses ...
