Technological Development to Improve Cross-cutting Seamlessness Earthquake Countermeasures

抄録

It is important to reinforce the "robustness" and "restoration capacity" of railways for them to be more resilient not only against expected earthquakes but also against anticipated earthquakes. It is therefore important to respond to the earthquake in four steps in terms of timing: response before the earthquake, emergency response at the time of the earthquake, initial response immediately after the earthquake and restoration/ recovery response after the earthquake. Since railway systems comprise numerous facilities, a range of seismic countermeasures have to be designed covering all components: civil engineering structures, catenary masts, and vehicles etc. Responses both at each stage of the emergency and in relation to each of these components during a seismic emergency should dovetail seamlessly. This report therefore introduces the latest technology that enables the establishment of seamless earthquake countermeasures.
