Study On Shannxi Highway Landslide Hazard Regionalization

Highway landslides occur more and more frequently in recent years in Shannxi province. The importance of landslide disaster prevention and mitigation is to find out a realistic solution to control it. Highway landslide disaster regionalization is a good method to control and assessment landslide disaster.First, This article take the Shannxi highway landslide disaster regionalization as the research content, has analyzed the relations between the landslide and natural environment, terrain, landform, hydrology, geology, meteorology, soil and vegetation, earthquake in Shannxi Province. At the same time, analyzed the landslide shape essential factor, the formed condition,the growth process, and induced the landslide classification, the disaster characteristic and some preventing and controlling measures. In this foundation, through the consult existing regionalization research results and the highway engineering standards proposed the principle and the method of Shannxi highway landslide hazard regionalization.Second, Carried on the influence factor analysis of highway landslide disaster division, and proposed the index system and implementation technology route of regionalization based on the system theory of region disasters, took it as the basis of reference and confirmation of the final achievements of regionalization, simultaneously some parameters also became the division key indexes.Finally, has unified division method of up-bottom and bottom-up, and man-machine interactive way, carried on the regionalization schemes research, proposed the highway landslide disaster hazards regionalization in Shannxi province, and has carried on the division appraisal explanation. Carried on the influence factor analysis of highway landslide disaster division, and proposed the index system and implementation technology route of regionalization based on the system theory of region disasters, took it as the basis of reference and confirmation of the final achievements of regionalization, simultaneouslysome parameters also became the division key indexes.
