Abstract

In order to recommend the mechanical smoke exhaust operation mode, Subway Environmental Simulation (SES) is used to predict the airflow of the inlet and outlet tunnel for the subway station. Fire Dynamic Simulation (FDS) is used the SES’s velocity boundary conditions to clarity the smoke exhaust effectiveness by the variations with mechnical ventilation system. We compared each 6 types of smoke exhaust systems for the result of smoke density and temperature distributions for 1.5m height from the subway station base in order to clarify the safety evaluation for the heat and smoke exhaust on subway fire.

본 연구는 지하철방재대책의 일환으로 터널구간에 설치된 환기기의 제연절환 운전모드 및 승강장 선로부 환기장치를 포함한 6종류의 제연운전모드를 대상으로 승강장에 정차된 열차화재 시나리오에 따라 3차원 실시간 화재시뮬레이션을 수행하여 제연방식별 열 및 연기전파특성을 규명함으로서, 승강장에서 열차 화재 발생시, 승객이 안전하게 최적 대피가 가능한 환기기의 제연절환 조합운전의 도출을 목표로 한다.
