With the rapid development of transportation infrastructure construction,highway tunnel engineering is facing many challenges when passing through complex geological conditions,among which the excavation construction of fully weathered fault fracture zone is particularly critical.Due to its high degree of fragmentation,instability and low bearing capacity,this kind of geological condition brings great safety risks and technical problems to tunnel construction.Therefore,it is of great significance to explore and optimize the excavation construction technology of the fully weathered fault fracture zone of highway tunnels to ensure construction safety,improve construction efficiency and control engineering costs.The purpose of this paper is to discuss in detail the excavation construction technology of the fully weathered fault fracture zone of highway tunnels,analyze in detail from the aspects of advanced support,excavation methods,grouting reinforcement and construction monitoring,and put forward specific technical measures to ensure construction safety and construction quality.
