Abstract
Seismic stability has not been considered in the design of traditional culverts in Japan. In recent years, however, the construction of precast arch culverts, which include hinges in the main body and are outside of the range of conventional culverts, has been increasing. In this study, large-scale shaking table tests, using a strong earthquake response simulator, were conducted to clarify the seismic behavior of a three-hinge precast arch culvert. Furthermore, the inner space displacement and the earth pressure of the culvert were measured at each construction stage. From the results, it was found that the modification mode of the component changed according to the banking height and that the culvert behaved as expected in the construction stage. Moreover, it was confirmed that the hinge part did not break prior to the ultimate behavior of the arch element during a large earthquake.
