Problems solved by technology

[0002] Existing research on train disasters in subway tunnels mainly focuses on the fire scene when there is no train in the tunnel or the train is blocked. A dynamic process, there is currently a lack of research on this aspect
In addition, the research on disaster types and risk prevention and control of subway tunnel trains mainly focus on the scene of fire, while there are relatively few studies on other disaster scenarios and multi-disaster coupling scenarios
Moreover, the research on tunnel train fires is mainly based on numerical simulation methods, and the design of fire scenarios and boundary conditions is highly subjective, lacking the support of field experiment data, and it is difficult to provide guidance for actual design schemes

Abstract

The invention discloses a subway tunnel train operation state and disaster coupling simulation system, which comprises a tunnel main body, a train model, a disaster generation system and a test measurement system. The train model is placed on a guide rail at the bottom of the tunnel main body, and the running speed of the train model is changed through a driving device. The disaster generation system comprises a fire source and an earthquake simulation device, the fire source is arranged in the train model, the earthquake simulation device comprises a simulation box placed on an earthquake table, the tunnel main body is placed in the simulation box, and an overburden layer is laid on the upper portion of the simulation box; the test measurement system comprises a temperature sensor, a gas component analyzer, a flow velocity sensor and a pressure sensor. According to the invention, simulation is carried out by setting parameters such as a train operation state and an earthquake grade, environmental parameters and train operation parameters in a tunnel are acquired, hidden risks under coupling of fire disasters and earthquake disasters are researched, and theoretical and technical supports are provided for subway engineering design, train operation safety and personnel evacuation.
