Study on Gas Leakage Diffusion in Adjacent Underground Space of Gas Pipe Network
With the passage of time and the influence of force majeure factors,the buried gas transmission network may leak,which will lead to the accumulation and diffusion of gas in the adjacent underground space.In order to investigate the diffusion behavior of gas in adjacent underground space after leakage of underground gas pipeline,the effects of different wind speed and atmospheric stability on gas leakage diffusion concentration distribution were studied by means of gas leakage model and high-speed diffusion model.The results show that the concentration of gas in the pipeline decreases rapidly after gas leakage.With the same atmospheric stability,the increase of wind speed will accelerate the gas diffusion and reduce the gas concentration in the pipeline.At different atmospheric stability levels,the lower the stability level,the slower the air flow,and the easier it is to cause gas accumulation.
