摘　　要：通过工程实例对山区隧道穿越段的岩土层调查,查明工作区范围地层岩性、岩层产状、构造及不良地质对隧道通过的影响程度,分析隧道所穿越的岩土层的隧道围岩类别,为隧道穿越工程初步设计提供所需的相关工程地质依据和工程设计所需的岩土工程参数等,对山区隧道的设计施工具有一定的借鉴作用。Based on the investigation of rock and soil layer of tunnel crossing section in mountainous area,this paper finds out the influence degree of stratum lithology,rock occurrence,structure and unfavorable geology on tunnel passing through the working area,analyzes the tunnel surrounding rock category of rock and soil layer crossed by the tunnel,and provides relevant engineering geological basis and geotechnical engineering required by engineering design for preliminary design of tunnel crossing engineering parameters,etc..It has a certain reference for the design and construction of tunnel in mountain area.

关 键 词：山区 工程地质 隧道 隧道围岩
