摘　　要：为优化太行山隧道通风设计方案,准确确定太行山隧道合理的需风量,通过对太行山隧道的交通量调查、国内机动车国标体系中烟尘颗粒物(PM)和一氧化碳(CO)减排进程、太行山隧道重载LNG货车计算的优化分析,提出了优化后烟尘颗粒物(PM)年递减率仍维持初步设计的3%不变,折减年限控制在2035年,根据实际调查情况,将重载LNG货车按照汽油车计算需风量,重载LNG货车占比按30%控制的方案。并将优化后的需风量与采用PIARC 2019标准测算的该项目需风量进行对比分析,最终确定太行山隧道的需风量采用优化烟尘颗粒物后重新测算的需风量。To optimize the ventilation scheme of Taihang Mountain Tunnel and precisely determine the reasonably required airflow in the tunnel,this paper analyzed the investigation of traffic flow in Taihang Mountain Tunnel,emission reduction of particulate matter(PM)and carbon monoxide(CO)in China′s national standard system of motor vehicles,and heavy load LNG truck calculation in Taihang Mountain Tunnel.It was suggested to remain the annual decline rate of optimized PM at 3%of the initial design,control the reduction age limit to 2035,calculate the required airflow of heavy load LNG trucks as that of gasoline trucks,and control the proportion of heavy load LNG trucks of 30%.Comparing the optimized required airflow to that calculated by the standard of PIARC 2019,it was determined that the recalculated PM-optimized required airflow was adopted in Taihang Mountain Tunnel.
