Abstract

<p> We analyzed seismic damage data on sewer buried pipelines at Atuma, Abira and Mukawa in Hokkaido subjected to strong ground motions in the 2018 Hokkaido Iburi Tobu earthquake. We revealed the characteristics of the damage ratio to the ground motion intensities from view of points of pipe types, diameter and classification of microtopography, and the relations of multi-variates on the damage ratio. Further we analyzed the dependency of the damage ratio on the ground motion intensities and modeled the trend of damage ratio data by using PGA, PGV and instrumental seismic intensity IJ.</p>
