摘要
将Scott-Hinsley回路法应用到平导半横向通风方式的解算中,以图论为基础,以风流运动的基本定律为依据,利用Gauss-Seidel迭代逐次求解回路修正风量,直到获得接近方程组真实解的渐进风量.针对公路隧道通风系统的特点在回路中考虑了交通风压的作用,并编制了相应的可视化解算程序.工程计算结果表明,Scott-Hinsley回路法能很好地解决平导半横向式通风计算问题,并可迅速、准确地实现横通道的风量和风阻的反复动态调节计算.
Scott-Hinsley loop algorithm is used in the calculation of the parallel-heading and semi-transverse ventilation mode in this paper. This method uses the Gauss-Seidel iterative method to solve the successive adjustment air volume in order to get a group of air volume values close to the real values of the equations. The influence of traffic wind pressure on the ventilation network is considered based on the own characteristics of highway tunnel. And the visual calculation program is developed. The calculation results show that Scott-Hinsley loop algorithm can easily solve the ventilation system calculation problem of the parallel-heading and semi-transverse ventilation mode, and can also adjust air volume and wind resistance of the cross passage for the repeated and dynamic calculation quickly and accurately.
