Outline of Final Research Achievements

Earthquake damage to several precast arch culverts installed in embankments was reported after the 2011 Great East Japan Earthquake. In this study, dynamic centrifuge model tests and numerical analyses were conducted to clarify the mechanisms causing seismic disaster to the culverts. From the results, it is confirmed that high overburden stresses can suppress the seismic behavior of the culverts near the mouth. Moreover, when the culverts and the embankment are obliquely-crossed, the asymmetrical earth pressure acting on the culverts is detrimental to the stability of the culverts.
