摘　　要：为解决北京市东六环路隧道通风问题,结合工程实际,综合考虑隧道需风量、环评要求、工程造价、办公和居住功能组团等影响因素,对隧道通风排烟方案进行综合比选,最终确定采用全纵向通风+重点排烟+空气净化(明挖段纵向排烟)方案,并利用隧道通风模拟软件IDA-RTV对制约采用全纵向通风方案的关键因素进行模拟分析。研究结果表明,该方案可提供人员尚可接受的隧道内环境,隧道污染物排放质量浓度满足环评要求。该研究成果可为今后同类型工程通风方案比选提供工程实例,具有较高的参考价值。In order to solve the ventilation problem of the East Sixth Ring Road Tunnel in Beijing,combined with the actual engineering,and considered the factors such as tunnel air demand,environmental impact assessment(EIA)requirements,project cost,office and residential functional groups,a comprehensive comparison and selection of tunnel ventilation and smoke exhaust schemes were carried out.Finally,the full longitudinal ventilation+key smoke exhaust+air purification(longitudinal smoke exhaust in open cut sections)scheme was determined.The key factors restricting the adoption of the full longitudinal ventilation scheme were simulated and analyzed by the tunnel ventilation simulation software IDA-RTV.The research results indicate that this scheme can provide an acceptable tunnel environment for personnel,and the quality concentration of tunnel pollutant emissions meets the requirements of EIA.This research result can provide engineering examples for the comparison and selection of ventilation schemes for similar projects with high reference value in future.
