Abstract

The invention provides an experiment platform for simulation of control over fire smoke at key connection positions of a subway station. The experiment platform for simulation of control over the fire smoke at the key connection positions of the subway station comprises a simulated station hall layer, a simulated platform layer, a simulated tunnel rail traveling layer, a simulated subway train, a ventilation and smoke discharge system, an air curtain system and a fire parameter measurement system. By the adoption of the experiment platform, study on a series of basic theories such as the flowing characteristics of fire smoke, generated when a fire disaster occurs on a subway station, at the key positions where a platform, a station hall and a tunnel rail traveling area are connected and control mode optimization and engineering practical problems can be conducted; a complete solution to study on the evolvement rule of the characteristic parameters such as the effectiveness of a technology for controlling the fire smoke at the key connection positions of the subway station, the temperature field and the poisonous gas concentration field in the scene that fire disaster occur on subway train fire-prevention parking stations and a subway station platforms is provided.
