Abstract: The stability of different types of highway slopes are studied by considering the three-dimensional topography; soil strata to be cut, construction measures; instrumentation probes; effect of highway bridges and tunnels; as well as groundwater table. The threedimensional visualized slope analysis information database was established by based on the weathered zone and soilrock interface along highway alignment. The paper introduces the application of the databased in the mitigation of landslides along FuNing Expressway. The database provided the information platform that integrating the highway geology, slope cut and construction as well as monitoring.
