Abstract
GRS integral bridge is applied for the first time as a railway structure in Hokkaido Shinkansen, and long-term and under-construction measurement are being carried out.From the characteristics of the GRS integral bridge, tensile displacement to geotextile occurs repeatedly by forced displacement due to expansion and contraction of concrete action.In addition, the possibility of tensile displacement to geotextile in the displacement-to-back direction of the approach block is caused to act is concerned.In this paper, to organize the data obtained from the long-term dynamics measurement, for the displacement situation back embankment and stretching behavior of the bridge part that affects the tensile displacement of geotextile , and the behavior of the actual structure was discussed.
