A Set of Survey Technology and Engineering Application for Long and Deeply Buried Karst Tunnel in Canyon Areas
In order to solve the survey problems caused by the steep terrain,complex strata,and geological conditions of deep buried karst tunnels in deep canyon areas,it is proposed to use the"space-air-ground"exploration technology to gradually construct and improve the karst geological body model from the"point line surface"dimension,and carry out engineering geological analysis,relying on the Chongqing Wuxi to Shaanxi Zhenping expressway project.The massive project practice has found that analyzing from the spatial geological body model can effectively solve major geological problems such as tunnel route corridor selection,surrounding rock classification,dynamic and static karst water inrush,water environment impact,etc.,better serve engineering design,and provide reliable geological technical support for construction and construction management.
