摘　　要：雅康高速公路二郎山隧道隧址区内的断层活动性对工程的设计和建设有着直接的影响。综合分析了野外对断裂的调查、ESR测年、石英形貌扫描(SEM)、断层气测量等资料,结果表明,二郞山隧道隧址区内的断层均无活动性,对工程建设基本无影响;隧址区内的挤压破碎带影响了岩体的完整性,工程中应主动避让或采取措施稳固岩体。The activity of main faults in the field of Erlang mountain tunnel in Yakang highway is directly affecting the engineering design and construction. With the integrative analysis of geologic field work of the faults, ESR dating, scanning of quartz shape（SEM） and fault gas measurement, we find that all faults in the field of Erlang mountain tunnel have no perceptible activities. So they have little influence to the engineering construction. But the crushed zone in tunnel station affects the integrality of rock mass, in engineering, it is necessary to take initiative way to keep away from these places or take measures to stablish the rock mass.
