摘　　要：基于地层岩性、地质构造、水文地质特征等分析,对XZN隧道工程地质条件进行综合评价。结果表明,XZN隧道穿越的断层、裂隙、岩溶、危岩落石、软土和红黏土是重要的不良工程地质条件,地下水危险程度以中危险区为主,断层和节理发育不仅影响隧道的稳定性,还为地下水运移提供了通道。在此基础上,提出了针对危险岩溶、地下水、地质构造、环境工程等方面的隧道施工建议。Based on analyses of lithology,geological structures,hydrogeological characteristics,etc.,a comprehensive evaluation of the geological conditions for XZN Tunnel Project was conducted.The results indicate that faults,fractures,karst formations,rockfall hazards,soft soils,and red clay along the XZN Tunnel alignment are significant adverse geological conditions.The degree of groundwater hazard is mainly in the middle danger area.The development of fault and joint not only affecting tunnel stability,but also providing pathways for groundwater migration.Based on these findings,recommendations for tunnel construction are proposed,focusing on addressing hazards related to karst,groundwater,geological structures,and environmental engineering aspects.
