Outline of Final Research Achievements |
Large-diameter pipelines had damage during the 2011 off the Pacific coast of Tohoku earthquake in March 2011 and its aftershocks. Water outage was caused in wide area for a long term. This study focuses on (1) damage to flexible joint of the water-pipe bridge due to strong ground motion and (2) damage to water-pipe bridge due to tsunami wave among the damage cases for the large-diameter pipeline. These studies on damage mechanism of large-diameter pipeline were conducted by field investigation of microtremor observation to the bridge and subsurface ground and by numerical analysis.
