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 Testing of Exhaust CO and Smoke from Plateau Tunnel Construction Machinery Works have important engineering value for the matching of the number of excavators, loaders and dump trucks required for tunnel ventilation system design and tunnel construction. On the basis of the first long tunnel of China Railway under the grid line of Segovia - Guanjiao tunnel, on-site tests were conducted on the emission of CO and smoke from excavators, loaders and dump trucks. The test results were in the construction specifications of railway and highway tunnels, “Altitude correction coefficient ” provides the basis and reference for the value in the range of 3600 ~ 3800m, which is of certain reference to the construction of the tunnel in the plateau area in China.
