In order to enhance the intelligent construction level of tower foundation, a new prefabricated helical anchor foundation is put forward, and the load-bearing performance of a new type of prefabricated helical anchor foundation under design loads is studied. A finite element analysis models of both the new prefabricated helical anchor foundation and the conventional cast-in-place helical anchor plate foundation are established using ABAQUS software. The research findings indicate that compared to the conventional cast-in-place helical anchor plate foundation, the new prefabricated helical anchor foundation significantly reduces the amount of concrete and steel reinforcement required while maintaining a similar load-bearing capacity under design conditions. The results of this study can provide valuable guidance and reference for the practical application of prefabricated helical anchor foundations in engineering projects.
