| | Abstract | | When the safety of railway facilities and running vehicles are threatened by the large shaking of ground motion along the railway during earthquakes, the railway operators stop trains as soon as possible. After the safety of trains operation is ensured by a cautious inspection patrol along the railway section, the trains operation is resumed. To confirm visually the damage of railway facilities and deformation of railway tracks in the inspection, it may take a lot of time. It is necessary to carry out the safety inspection more precisely and effectively, for shortening downtime of regular trains operation. Therefore to comprehend exactly the characteristics of earthquake ground motion along the target railway, the rapid estimation of the shaking is required strongly. In this study, we selected the Miyazaki maglev test line located in the middle coast of Miyazaki prefecture, as a target railway. We tried to estimate the continuous linear S-wave velocity structures and seismic motions on the Miyazaki maglev test line. And we confirmed the validity of the continuous linear S-wave velocity structures and the estimation of earthquake ground motions on the target railway, through the comparison to the observed earthquake ground motions. |
