EMERGENCY RESTORATION STRATEGY FOR WATER DISTRIBUTION SYSTEM AFTER EARTHQUAKE DISASTERS

Abstract

 Earthquake resistance of the water pipe distribution network has been recently required for earthquake disaster risk reduction. In particular, from the perspective of disaster resilience, it is considered necessary to identify the effects of Material and human resources and restoration priorities on the restoration process. The objective of this study is to develop a numerial simulation model that can express the water sup-ply situation of the daily pipe network after the earthquake disaster. The discretized damage estimation focusing on individual pipe, the pipe network analysis model after the earthquake and the emergency res-toration model was developed, and verified the restoration process that changes depending on the number of emergency restoration groups and restoration priority. The results show that sufficient number of group and prioritizing the pipelines in a regional mesh with a large population of water outage would enable ef-ficient restoration.
