摘要：In order to evaluate and increase the capacity of geocell that is widely used in ground improvement, the optimization research is conducted based on the node shapes and size of 3D printed geocells in this paper. Firstly, the finite element modelling is established and simulated by finite element analysis software CATIA and then comparison results of the simulation among stress distribution, mechanical characteristics and working conditions of nodes with different shapes and sizes are made. Furthermore, based on the lateral effect of geocell, the experiment on the optimized 3D printed geocell is carried out under variations of the numbers of holes, loading rates and different depths of soil deposits. It should be noted that the force characteristics and working conditions need to be considered while using or designing structure-optimized reinforced material to ensure the stability and strength of the structure. Finally, the simulation and experiment results show that the strength of the geocell is affected by different shapes and diameters of nodes, and the optimization can significantly enhance the performance of geocell.
