抄録

In the 1995 Kobe Earthquake disaster, the roads and railway facilities in the Kobe area experienced severe damage. And, in the disaster emergency response and restoration process of these lifeline facilities, it has been reported that damage to roads and railways have interrelationship effect (interaction) to the damage in different type of lifelines, such as electricity, gas, water, sewers, telephones. Even now, about 30 years after the case in Kobe, it is easy to imagine that similar phenomenon will occur in case of a large earthquake disaster. The Lifeline Network Kansai (LiNK), which consists of lifeline related organizations and researchers in the Kansai region, examined the past damage and the current installed countermeasures, and the possible interaction of various types of lifeline systems.
