摘　　要：以实际工程为依托,结合该项目长距离施工通风,介绍了秦岭隧洞辅助坑道的总体布局、长距离施工通风的特点及面临的困难。通过对前期施工通风研究,结合现有施工通风耗材的性能特点,重点论述了现有施工通风技术存在的问题及解决方法。结合本项目提出了不同的施工通风方案,并对提出的主要方案进行施工通风计算分析,提出了推荐方案并给出了建议。Based on engineering practice, this paper introduced the general layout of auxiliary galleries, characteristics of long distance construction ventilation and facing challenges are presented in detail. According to the preliminary research results, combined with the performance characteristics of supplies, the paper focused on the existing problems and measures including the ventilation control standard, parameters of baffle duct ventilation, calculation of air leakage rate during the process of construction ventilation. Different construction ventilation schemes and corresponding calculations are compared. The recommended scheme and the corresponding measures are proposed.
