摘要
分析了燃气在土壤中的扩散原理与影响因素,结合泄漏量的计算模型,建立了埋地燃气管道泄漏后的一维扩散方程。通过量纲分析的方法对扩散方程求解,得到了燃气在土壤中的泄漏扩散浓度表达式,通过实例计算分析得出了燃气在土壤中的泄漏扩散规律。
The diffusion mechanism of gas in soil and the influencing factors are analyzed. The one-dimensional diffusion equation of buried gas pipeline leakage is established based on leakage calculation model. The equation is solved by the dimensional analysis method, and the expression of gas leakage concentration in soil is deducted. The leakage and diffusion law of gas in soil is obtained through analyzing the example calculation.
