Subway long and large interval fire experiment system and method

Abstract

The invention discloses a subway long and large interval fire experiment system and method. The subway long and large interval fire experiment system includes a subway tunnel entity unit, a train unit, a hot smoke generation unit, a ventilation smoke evacuation unit and an experiment measurement data acquisition unit, wherein the train unit is arranged in the subway tunnel entity unit; the hot smoke generation unit is used for generating the fire source and the smoke which are required by a fire experiment; the fire source and the smoke are generated in the train unit; the ventilation smoke evacuation unit is arranged on the subway tunnel entity unit, and is used for discharging the smoke in the subway tunnel entity unit; and the experiment measurement data acquisition unit is used for acquiring the fire experiment data. The subway long and large interval fire experiment system can simulate a fire accident in a subway long and large interval, thus saving the cost for fire accident simulation, and can optimize tunnel ventilation and smoke evacuation design of the subway long and large interval.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a fire experiment system and method in a long section of a subway. Background technique [0002] The line spacing in the long subway section is large. Once a fire occurs, the smoke will spread quickly, the smoke exhaust system has limited smoke exhaust capacity, and it is inconvenient for people to evacuate and escape. The study of accident scenarios such as fire spread and fire smoke diffusion in long subway sections has good guiding significance for the optimization of ventilation and smoke exhaust modes and personnel evacuation schemes under fire scenarios in long subway sections. [0003] For subway tunnel fire experiments, it is very difficult and uneconomical to construct a full-scale subway tunnel fire experiment model; The interval tunnels are basically in operation, so it is inconvenient to conduct fire experiments, and the real situation of each subway interval tun...

Problems solved by technology

[0003] For subway tunnel fire experiments, it is very difficult and uneconomical to construct a full-scale subway tunnel fire experiment model; The interval tunnels are basically in operation, so it is inconvenient to conduct fire experiments, and the real situation of each subway interval tunnel is not the same. The fire simulation research results of a certain subway interval tunnel may not be applicable to other subway stations. It is very time-consuming and expensive to simulate fire scenarios for site preparation and collect relevant data

Many scholars at home and abroad have carried out numerical simulation research on the fire spread in the long-term subway section through CFD numerical software, but the smoke exhaust mode in the long-term section needs to be verified
