Abstract

The seismic damage data of flat roads subjected to strong ground motions and liquefaction in the 2011 off the Pacific coast of Tohoku earthquake were analyzed and the fragility curves describing the probability of occurrence of a failure to flat roads were derived based on probabilistic modeling. Flat roads distributed in a seismically potential liquefied area have a risk to show the relatively higher value of damage-ratio index when PGV of 30 cm/s or instrumental seismic intensity, IJ of 5.0, that is the relatively lower value of seismic intensity.
