Abstract

 The 2004 Niigataken Chuetsu earthquake, the 2007 Niigataken Chuetsu offshore earthquake and the 2016 Kumamoto earthquake caused severe damage to the telecommunication pipelines in bridge section. In this study, data set was constructed from view of points of bridge type, construction year, bridge length, micro-topography and liquefaction occurrence for the telecommunication pipelines exposed to previous seismic damage, In addition, the peak ground acceleration PGA, the peak ground velocity PGV, the value of spectral intensity SI and the instrumental seismic intensity IJ, which are indicators of the ground motion intensity, are selected and the relation between these indicators and the damage rate was revealed.
