摘要：

Er Lang Shan tunnel is the most absolute altitude constructed highway tunnel in china, which is firstly used the semi-transverse ventilation system, is characteristic of extensive length, higher absolute altitude, multivariate climate, two-way traffic and complex wind stream. Based on FEM software CFDesign, the distributed losses, the conflux losses and the shoot of jet fans in the semi-transverse ventilation system of Er Lang Shan highway tunnel are studied by numerical simulation. Part resistance coefficients that numerical simulation of the semi-transverse Ventilation under various work condition needs are obtained.
