摘要： 结合某公路隧道，采用调查研究与数值分析方法，从研究高应力、高烈度地区活动断层的活动性出发，详细研究活动断裂带工程地质、水文地质背景及岩土体的物理力学性质，研究活动断裂错动位移对隧道复合式衬砌结构的影响机制、活动断裂错动位移作用下隧道结构变形与力学行为，基于复合式衬砌结构在错动位移下的影响机理，提出隧道变形破坏的评价标准，为工程建设提供技术支撑。

Abstract: This paper presents a case history of the analysis and design of a highway tunnel through an active fault zone. The tunnel was modelled through the combinations of geological investigations and numerical analysis. The engineering geology, hydrological as well as geotechnical aspects of the proposed tunnel were studied from the high rock mass stress and high activity of the fault point of view. The impact of displacement magnitude of the fault zone on the composite tunnel lining structures, as well as the deformation of the tunnel are numerically simulated. The criteria for the tunnel deformation failure are classified.
