Currently, research on the influence of different concrete expanded plate (CEP) pile parameters on bearing capacity under vertical pressure is primarily focused on the problem of CEP single pile, with little research on the problem of the CEP pile group. Therefore, this work uses ANSYS software to perform finite element simulation analysis of the CEP pile group. The effects of different plate positions of CEP double pile under vertical pressure on the damaged state of soil surrounding the pile and the compressive bearing performance of CEP double pile are discussed. By completing a comprehensive analysis of the displacement cloud diagrams and load–displacement curve of the CEP double pile, the pile-soil force mechanism and failure law are obtained, as well as improving the CEP double-pile carrying capacity calculation mode. It provides theoretical support for the promotion and application of CEP piles in actual engineering. The results show that when the pile spacing is fixed, the bearing capacity of the bearing plates of the CEP double pile is higher when the bearing plates are set at the same position than when the plate position is misaligned. When the plates are set at the same position, the closer the bearing plate is to the pile end, the greater the compressive bearing capacity of the CEP double pile.
