摘要
长大公路隧道常见的通风方式有纵向式通风、半横向式通风和横向式通风,其中,半横向式通风和横向式通风及多竖(斜)井纵向式通风的传统计算方法较为复杂。基于.net环境的C#面向对象编程语言,应用矿井通风网络解算中较为成熟的Scott-Hinsley回路算法,在考虑了自然风压、尤其是交通风压对隧道通风网络的影响之下,设计开发了公路隧道风网解算可视化软件,并通过实际工程的实例计算,表明该软件具有计算量小、使用方便的特色,
The regular ventilation styles in long highway tunnel are plenum ventilation, transverse ventilation and semitransverse ventilation, the traditional computational methods of semi-transverse ventilation, transverse ventilation and plenum ventilation with a hand of shafts are relative complicated. Based on the C # OOP（Object Oriented Programming） language under the. net environment, a relative mature loop arithmetic, namely the arithmetic of Scott-Hinsley, which was used for many years in the calculation of ventilation network mainly in coal mine, was used to develop the visual calculation software of tunnel ventilation network. The calculation software introduced in this paper took into account the impact of natural wind pressure and traffic wind pressure on the tunnel ventilation network, where the traffic wind pressure may play an important role in the balance of wind pressure in the ventilation network when the amount of transport is considerable. Finally, a project example was displayed and computed here to verify the function of this software, including the convenience and the simplification of computation.
