摘　　要：以十漫高速公路隧道为工程背景,用《公路隧道设计规范》、Q法、RMR法对火车岭隧道围岩进行分级研究,并对分级结果进行比较分析;从方法的内涵、适用条件分析分级结果在本隧道的适用性,以期在实践中减少人为主观因素影响,使分级指标的选取及取值更合理,采取分级验证对设计资料进行修正,以能够更好指导后续工作。The authors study the surrounding rock classification of Huocheling Tunnel on basis of Road Tunnel Design Specification, Q classification method and RMR method and comparatively analyze the classification results. The authors also analyze the adaptability of these classification results in this tunnel in terms of the connotations and application conditions of the classification methods, in order to reduce subjective factors in practice and make the selection of the classification indexes more reasonable and to modify design documents from classification verification. The classification resuhs can help to guide the implement of following works of this tunnel.
