Northwest mountain area of Hubei province is landslide-prone area in China. By transportation

utilities

energy

resources and other infrastructure construction greatly being underway

a large number of excavation-type and reservoir storage-type landslide may be triggered in future. The swift establishment of a synthetical classification system for the regional slope/landslide is the basic work for further researching the regional slope/landslide of the development of the law of distribution

deformation & failure mechanism

space-time forecasts and the corresponding treatment policy. The synthetical classification system can also provide basic achievement data for future in-depth study of the region slope/landslide problem. This article first discusses the establishment of the regional slope/landslide of the basic principles of a synthetical classification system and clear the three most important characteristics of building the regional slope/landslide system. After that

this article presents multilevel block diagram of the synthetical classification system. After in-depth analysis of the typical slope major categories of the synthetical classification system

this article preliminary classifies 19 typical slopes. Some typical engineering examples are listed. The deformation

failure pattern and mechanism of those kinds of slopes/landslides in this region is preliminary analyzed. Some suggestions for analytical method and countermeasures of those kinds of slopes/landslides are put forward.
