Abstract
In order to study the bearing performance of cantilevered circular bite piles under excavation, this paper takes the underground garage. In order to study the bearing performance of cantilevered circular bite piles under excavation, this paper takes the underground garage support project of Nanchang Bayi Square as the research background and conducts the indoor model test of cantilevered bite piles under horizontal load. The test results show that under horizontal load, with the increase of soil depth, the bending moment of the bite pile is increasing first and then decreasing, and the bending moment reaches the maximum near the excavation surface. The lateral soil pressure is approximately linearly distributed, and the horizontal displacement of the pile top increases non-linearly with the increase of horizontal load. The test results can effectively optimize the design of circular occlusion piles.
