“…This constitutive model was developed for simple modeling without change of parameters of stress-induced anisotropic in soil due to soil density, over consolidation ratio, soil structure given by natural accumulating process and various stress histories. These profiles were decided by isotropic consolidation test and triaxial compression test for Edosaki sand (Sawamura et al, 2016). Table 1 shows the parameters of embankment.…”

“…On the other hand, the hinged arch culvert is likely to collapse due to the deviation of hinge, which has emphasized the interest of the seismic stability of the hinge structure; e.g. Sawamura et al, (2016) aimed to clarify the damage morphology and the ultimate state of the three-hinged arch culvert through the large table shaking tests on 1/5 model of three-hinged arch culvert. As results, the deviation of hinge is unlikely to occur in advance of the failure of arch members even after the strong earthquake which caused more than 7 % of shear strain of ground.…”

The Great East Japan earthquake (11 March 2011) caused loss of serviceability on many three-hinge type of precast arch culverts, which indicated importance of clarification of its damage mechanism. However, there is no effective seismic evaluation method available in the current design criteria of the precast arch culverts for the observed damages correlated with the inertial force to the longitudinal direction. On the other hand, our research group has conducted the series of dynamic centrifuge tests on the precast arch culverts to observe the seismic behavior in culvert longitudinal direction. As the results, the seismic behavior in the longitudinal direction of the precast arch culverts is controlled by their longitudinal, structural connectivity and confining stress of the culverts from the embankment. In short, in a numerical analysis, the longitudinal seismic behavior of the precast arch culverts should be governed by these effects due to longitudinal, structural connection and overburden of culverts.Therefore, in the present study, 3D elasto-plastic finite element analyses for three-hinge type of precast arch culvert were conducted to develop a new evaluation method for the longitudinal, seismic performance of the precast arch culverts. In these analyses, the structural connection is modeled by non-linear spring element and the slip and separation between the culvert and the soil is modeled by joint element. From the analysis results, the patterns of the deformation of the culverts and the embankment and axial force behavior of the structural connections due to the various embankment shape can be evaluated.

“…As for the culvert transverse direction, basic knowledge of numerical analyses has been obtained (Wood, et al, 2000), and the critical state of the hinge structure and the precast member in precast arch culverts has been grasped (Sawamura, et al, 2016). As for the culvert longitudinal direction, studies have only been conducted for a specific type of precast arch culvert (Saito, et al, 2005), although seismic disasters in this direction are the principal cause of damage to road embankments (Tokida, et al, 2007).…”

The seismic performance of precast arch culverts in the culvert longitudinal direction has not been clarified even though the principal cause of embankment disasters is earthquakes in this direction. On the other hand, precast arch culverts are constructed by continuously arraying and connecting each segment. That is why the dynamic behavior of precast arch culverts in the culvert longitudinal direction is believed to depend heavily on the method with which the culverts are connected. Accordingly, the aim of this study is to evaluate the influence of the connecting condition of precast arch culverts on the dynamic behavior in the culvert longitudinal direction by conducting dynamic centrifuge tests. It is found that connected culverts, compared with separated culverts, are relatively advantageous in decreasing the enlargement of the bending moment on the bottom slab of the arch culverts which leads to cracks in the culverts.
