抄録

In this paper, we conducted a two-dimensional effective stress analysis in consideration of the interaction between the ground and the structure for the Kurumakaeri Bridge which is located in the caldera of Mount Aso. From the results of the analyses, it is confirmed that the ground around the abutment subsided by about 26 cm due to the deformation of the soft volcanic ash soil. Furthermore, it is confirmed that the collision between the superstructure and the abutment happened because the abutment moved to the front side. Due to this movement, the deformation of about 34 cm occurred at the rubber bearing after the earthquake ended.
