Analysis of Disaster-Prevention Index System of Urban Underground Transportation Junctions

On the basis of current situations of urban underground transportation junctions and combining with on-site investigation of Beijing Xizhimen transportation junction station, this paper puts forward the disaster-prevention index system of urban underground transportation junctions. Specific analysis is on the disaster index in four aspects: informational sign, fire-fighting equipment, evacuation capability and refuge. 17 indexes are extracted reflecting the disaster evacuation performance, the weights of each disaster-prevention index are defined by Analytic Hierarchy Process (AHP), and fuzzy comprehensive evaluation method is adopted to conduct comprehensive evaluation of safety performance. The established disaster-prevention index system has practical value and significance to improve the disaster-prevention capability of urban underground transportation junctions.
