Description

After Hyogo earthquake in 1995, bridge foundations have been reinforced by several kinds of methods. The method in which caisson foundation is reinforced by steel pipe sheet piles (SPSP) has been developed and practically constructed. However, the mechanism of load resistance of this foundation system and the effect of SPSP reinforcement has not been explained. In this research, centrifugal model tests on this foundation system were conducted to grasp the mechanical and deformation behavior under lateral loading. Influence of the size of SPSP wall on the magnitude of the ratio of flexural rigidity of the caisson foundation to that of SPSP reinforcement wall is concidered.
