DEVELOPMENT AND APPLICATION OF AN EVALUATION METHOD OF THE VULNERABLE SECTION TO THE EARTHQUAKE OF THE ROAD NETWORK

Abstract

 At the time of earthquake occurred, the important road section such as the emergency transportation road is likely to impassable. Because of this reason, it is assumed that bad influences such as the detour or the isolation will occur. Consequently, it is important to evaluate the road section vulnerable to earthquakes. In this study, an evaluation method of the vulnerable road section to the earthquake of the road network is developed and it applied to evaluation of the vulnerable road section of emergency transportation road network. As a result of this analysis, the utility of this method became obvious.
