摘　　要：以弱基岩强构造区某公路隧道为研究载体,调查分析隧道结构变形破损状态,归纳结构变形的显著特征;通过研究隧址区的区域地质构造、岩体岩性和产状、地下水等水文地质环境,分析导致隧道变形破损的内外因素;通过三维数值模拟,研究隧道结构变形破损处治对策,为弱基岩强构造区隧道建设提供技术参考。Using a highway tunnel in a weak bedrock and strong structural area as the research carrier,it investigates and analyzes the deformation and damage status of the tunnel structure,and summarizes the significant characteristics of structural deformation.By studying the regional geological structure,rock lithology and attitude,and hydrogeological environment such as groundwater in the tunnel site area,it analyzes the internal and external factors that cause tunnel deformation and damage.Through three-dimensional numerical simulation,the treatment strategies for deformation and damage of tunnel structures are studied.It provides technical reference for tunnel construction in weak bedrock and strong structural areas.
