Code for design on operating ventilation of railway tunnel
鐵路隧道運營通風設計規范Then a one - dimensional unsteady incompressible flow with moving pollutant source model was proposed. the continuity equation, momentum equation and convection - diffusion equation were discredited using finite volume scheme. thus a software for predicting the air velocity and pollutant in railway double track tunnels was developed
接著,根據雙線鐵路隧道運營通風的特點,建立了一維不可壓縮非恆定流和流動污染源的物理模型以及山相應的連續性方程、動量方程和對流擴散方程構成的數學模型;在此基礎上,利用數值計算方法,編制了一套雙線鐵路隧道運營通風的數值計算程序。By analyzing the relation between the train passing capacity and tunnel length as well as tunnel slopes the upper and lower limits for installing mechanical ventilation in railway double track tunnel have been determined, which provides science foundations for the formulation the ventilation design norm for railway double track tunnels in operation
通過對列車通過能力與隧道長度和坡度關系的進一步研究,得出了內燃牽引雙線鐵路隧道設置機械通風的上、下界限,為雙線鐵路隧道運營通風設計規范的制訂提供了科學依據。Finally, based on the survey on the ventilation of double ( rack tunnels in operation representative parameters were selected and a series of computations were carried o ' ut to examine the train passing capacity of tunnels with different lengths and slopes
最後,根據對我國雙線鐵路隧道運營通風的調查分析,選擇具有代表性的參數,利用數值計算程序,對不同長度和坡度的隧道在自然通風情況下列車的通過能力進行了模擬計算。Because there are small openings and the three cracksin the concrete lining of gas tunnel, the gas should intrude into the gas tunnel built. this effect will endanger the transport safety. the authors study on the operation ventilation technology in the gas tunnel and put forward an economical, safety and effective ventilation plan, and therefore furnish a theoretical basis for the gas tunnel ventilation design in the future
由於瓦斯隧道混凝土襯砌本體中的細小孔隙和「三縫」等缺陷的存在,建成后的瓦斯隧道必然受瓦斯侵襲,這對運營安全危害極大,為此,本文對瓦斯隧道運營通風技術進行了認真研究,提出了經濟、安全、有效的通風方案,為未來瓦斯隧道的通風設計提供了理論依據。分享友人
