摘　　要：高原隧道工程机械尾气排放CO和烟雾的现场测试对隧道通风系统设计及隧道施工所需的挖掘机、装载机和自卸汽车数量的匹配有重要的工程价值。以西格线中国铁路第一长隧——关角隧道为依托,进行了多种挖掘机、装载机和自卸汽车CO与烟雾尾气排放的现场测试,测试结果为铁路、公路隧道施工规范中"海拔高度修正系数"在3600～3800m的范围内取值提供依据和参考,对我国在高原地区修建隧道有一定的参考作用。Field test for CO and smoke in emissions of construction machinery in tunnels is of important engineering value to the design of ventilation system in the tunnels and the numbers configuration of excavators, loaders and haulers equipped in the construction. Based on Guanjiao runnel in Xige line, the first long runnel in China's railways, field tests are conducted on CO and smoke in emissions of various excavators, loaders and haulers. The tests results provide basis and reference for value setting of 'amending-factor of elevation' from 3600m to 3800m in Construction Codes of Tunnels in Railways and Highways and are of referential functions for tunnels construction in domestic high lands areas.
