METHOD FOR ANALYZING FIRE DANGEROUSNESS OF RAILWAY TUNNEL

摘要

PURPOSE: A method for analyzing fire risk of a railway tunnel is provided to analyze the fire risk by predicting the probability of accidents, and comparing the predicted information with a standard value. CONSTITUTION: The past statistical data is inputted(S11). The tunnel information and train information of the analysis object are inputted(S12). The accident occurrence frequency about the tunnel length is predicted(S13). The number of deaths and the probability of accident occurrence over the number of deaths are generated. The FN curves express the probability of accident occurrence over the number of deaths and the number of deaths in a graph(S15). The data range with higher value than the standard FN curve is determined as having higher fire risk(S16).
