The invention relates to a leakage and explosion experiment system for a high-pressure buried gas pipeline in a tunnel. The system is composed of a tunnel model test field, a natural gas pipeline, a leakage device, a gas distribution unit, a concentration sensor, a free field pressure sensor, a visual window, a high-reflection camera, an ignition unit, a synchronous controller and a data acquisition unit. Through the system provided by the invention, the tunnel space diffusion law of the leaked natural gas of the buried pipeline in the tunnel, the flame propagation characteristics generated by ignition of the leaked natural gas in the tunnel, the flame frontal surface form and the tunnel exit free field pressure can be deeply researched; and serious consequences caused by leakage diffusion and burning explosion of the buried high-pressure gas pipeline in the tunnel are relieved.
