Device and test method for simulating effect of gas pipeline explosion on subway tunnel

The invention relates to a device for simulating gas pipeline explosion action on a subway tunnel, which comprises a detection frame, a simulated gas pipe, a simulated tunnel pipe, a measuring assembly and a sponge mat, the simulated gas pipe is transversely arranged at the upper part of the detection frame, a plurality of swing beads are arranged in the middle of the simulated gas pipe in an array manner, and the simulated tunnel pipe is transversely arranged at the lower part of the detection frame. One end of the simulation tunnel pipe extends out of the detection frame and is provided with an ejector rod, the measurement assembly comprises a measurement cylinder, the measurement cylinder is vertically arranged below the ejector rod, and the detection frame is filled with a sponge pad; the invention discloses a test method for simulating the effect of gas pipeline explosion on a subway tunnel. The test method comprises the following steps of A, arrangement, B, force storage, C, explosion simulation and D,
