Abstract: The highway and railway linear infrastructure construction will produce many engineering geological problems easily. The past, the future,by summarzing some typical cases of freeway, national and provincial highway and railway construction in Fujian, results show that：landslides(including ancient landslide resurrection),tunnel water inrush, soft soil are the major engineering geological problems of highway and railway engineering in Fujian province. Landslide problems are solved by strengthening the ancient landslide early identification and system survey, the implementation of dynamic design of monitoring feedback, and comprehensive treatment of three-dimensional drainage, load shedding and anti slip anchor retaining; Base on the comprehensive survey in the early stage, the key of prevention of water inrush in tunnel is early advance geological forecast warning monitoring and prevention of phase faults, rock fissures and karst caves in the tunnel construction; Through the survey reveals of the structure characteristics of the soft soil genesis, three-dimensional distribution and physical mechanics, the corresponding treatment are apllied in soft soil foundation of replacement, drainage consolidation, flexible pile, rigid pile, or structure of pile-plate, pile-raft and pile-net.
