Abstract

With the goal of saving materials, ensuring rapid construction, and ensuring controllable quality, a new type of single double-ribbed prefabricated assembly raft foundation is proposed by considering the structural characteristics of raft foundations. Currently, there is limited research on the mechanical characteristics of prefabricated raft foundation structures. This study establishes a comprehensive finite element model of the foundation and conducts model experiments to investigate the structural load-bearing characteristics of prefabricated raft foundations under V（vertical）-H（horizontal）-M（moment） composite load. It specifically focuses on analyzing the load-bearing capacity and failure modes of foundation rib beams, baseplate, and pillar supports. The results show that the new single double-ribbed prefabricated raft foundation structure has good load-bearing and structural mechanical properties, and the safety reserve can reach 1.44 times the design value. The overall stability of the foundation is good, and all indicators meet the design requirements of existing specifications. The junction between the column and the rib beam is a key part of the bearing and load transfer of this type of foundation structure, which should be paid attention to during the design and construction.
