The additional pile method is a technique used to reinforce existing foundations by piles and footings. The main problem with this method is that it takes a lot of time and effort to combine the existing foundation and the additional foundation. Another problem is that the design of this method cannot be sufficiently rationalized because the load share mechanism is unclear due to the generation of the pile group effect. The objectives of this study are to develop a new high-workability combining method and to investigate the load share mechanism of the reinforced foundation. In this paper, 1G seismic loading tests are conducted on group piles, namely, 4 existing piles and 6 additional piles. Then, a simulation analysis of the loading tests is performed. Finally, a parametric analysis that simulates the superstructure and the steel outer shell is conducted.
