Abstract

Steel grid is an effective reinforcement material for improving weak foundations and it is necessary to conduct in-depth research on its mechanism. Finite-discrete coupling method was used for numerical simulation of steel grid pull-out test in gravels. By analyzing the mechanical response of particles and steel grids near the soil reinforcement interface under overburden stress and comparing it with experimental data, it can be seen as an effective method for the simulation of steel grids. During the pulling process, a concentrated displacement zone gradually forms in the vicinity of the steel grid, which drives the soil to move in the pulling direction together. In addition, the contact force chain of the soil is concentrated on the front end, indicating that the friction and bearing resistance of the transverse and longitudinal ribs of the steel grid can significantly improve the interfacial strength.
