Abstract

The 2011 off Pacific coast of Tohoku Earthquake hit Tohoku and Kanto regions, and caused a number of liquefaction-induced damages to the residential houses, roads and life lines. This study investigated the factors on liquefaction-induced road damage in Urayasu city, east of Tokyo, where severe liquefaction occurred during the earthquake. In order to measure the road settlement, two sets of Digital Surface Models (DSMs) obtained by airborne LiDAR (Light Detection and Ranging) surveys before and after the earthquake were compared with pile-supported RC buildings and bridge piers as templates for aligning the two sets. The result showed that the extent of the road damage by liquefaction extracted by DSMs was reduced as the thickness of roadbed (pavement and subgrade) that could not be liquefied during the earthquake increased.
