| Research Abstract |
Multi-arch culverts embankment is a new type of filling structure where several precast arch culverts are installed continuously in the direction of the road extension. The key of the successful design is to estimate the practical interval between installed arch culverts and to clarify the interactive behavior between filling material and precast structure in considering the seismic influence. In this study, dynamic centrifugal model experiments and dynamic FEM analyses have been carried out to investigate the influence of spacing between multi-arch culverts and mechanical behavior under seismic conditions has been discussed. From the results, it was found out that the case with narrow unit interval has high rigidity as a whole because the volume in the fill part where the rigidity is comparatively small decrease and bending moment of arch culvert and deformation of surrounding soil become small.
