Abstract :
Er Lang Shan tunnel is the most absolute altitude highway tunnel in china, which was firstly used the semi-transverse ventilation system, is characteristic of extensive length, higher absolute altitude, multivariate climate and complex wind stream. Based on one-dimensional fluid mathematic models, the characteristics of distribution of wind field were simulated under diversity conditions such as fans, transportation stream and natural pressure. The maximal capability of process of vehicle jam under increase of fans and vehicle was also analyzed.
