摘　　要：了解兰渝铁路特长隧道内空气质量状况,以预防可能对隧道内养护人员产生健康威胁的有害因素。在铁路运营且避开隧道内机械通风开放时间,采用直读式仪器对12条特长隧道内物理因素(温度、湿度、气压、风速、噪声)、化学因素(CO、CO_(2)、O_(3)、NOX、SO_(2)、粉尘)及可吸入颗粒物(PM_(2.5)、PM_(10))浓度进行测量并与国家相关标准比较。结果表明,兰渝铁路特长隧道内气象条件良好,无高气温、高气压和超标噪声的影响;化学污染物(CO、CO_(2)、O_(3)、NOx、SO_(2)、粉尘)和可吸入颗粒物的浓度基本不超标。此次监测结果说明目前隧道内有害因素未对隧道内相关工作人员健康产生影响。To understand the air quality in the extra-long tunnel of Lanzhou-Chongqing Railway, so as to prevent harmful factors that may threaten the health of maintenance workers in the tunnel. During the railway operation period, avoiding the opening hours of mechanical ventilation in tunnels, the physical factors(temperature, humidity, air pressure, wind speed and noise), chemical factors(CO, CO_(2), O_(3), NOX, SO_(2), dust) and the concentration of inhalable particulate matter(dust, PM_(2.5),PM_(10)) in 12 extra-long tunnels were measured by direct reading instruments and compared with relevant national standards.The results showed that the meteorological conditions in the extra-long tunnel of Lanzhou-Chongqing line were good, and there was no influence of high temperature, high pressure and excessive noise;The concentrations of chemical pollutants(CO, CO_(2), O_(3), NOx, SO_(2), dust) and inhalable particulate matter were basically not exceeding the standard. The test results show that the harmful factors in the tunnel have no health impact on the related staff in the tunnel.
