Description
Sanriku Railway Haipesawa bridge is a new bridge alternative to the old one extensively damaged by the tsunami of the Great East Japan Earthquake. The new bridge is a new type bridge (GRS integral bridges); integral bridge with geosynsetic-reinforced soil (GRS) abatement.??Because of its structural system, i.e. highly statically indeterminate structure, it is concerned that the bridge with longer span may have larger influence on crack occurrence, caused by temperature deformation and shrinkage of concrete.?? This paper describes the measurement results of 2.5-year measurement and the observed knowledge from the measurement results. Considering these results, the timedependent mechanism of resistance of the GRS integral bridge was discussed.
