Well-being - And The Xunyang - Sichuan River Along The Highway Geological Hazard Assessment

With continuous development of human-bing society, people's life often is threatened by geologic hazards. For example landslide, devolution, debris flow and ground slit etc of geologic disaster have being increasingly take place,and intimidate people's life and properties.especially recent years,with rapid progress of westward's opening up,geologic hazards more and more prick up which are influenced by facters of nature and human being.In this background,it is very important that fatalness of geologic hazards of Ankang-Xunyang-Shuhe highway are estimated.This paper focuses on the core problem of the research of geologic hazards,disaster assessment,takes geologic hazards of Ankang-Xunyang-Shuhe highway as an exmple.As the same time,it links practical situation and chooses proper technique so as to ameliorate and innovate such problems in past critical evaluation of geologic disaster as low efficiency,bad accuracy,and waste of time and strength and to make disaster assessment of the highway informed and scientific.In the process of researching,the paper constructs judgement models of geologic hazards and make use of foundation info and technique (GIS,remote sensing video and database building etc)of disaster assessnent in order that gets fatalness conclusions,and then puts forward proposes.Fruit and content of the paper involve:(l)The environmental geologic condition of the highway geologic hazards developing is analysed,such as meteorology hydrology, configuration geomorphy,strata lithologic character, geologic structure, hydro-geology,neotectonic movement and earthquake etc;(2)The distributing laws of space and time and the main character of the highway geologic hazards are analysed based on introducing of the highway hazards developing status;(3)Foundation info and technique of critical evaluation of the highway geologic disaster are analysed which focuses on practical situation;(4)Fatalness developing intension of the highway geologic hazards is analyseed,takes geologic hazards of Ankang-Xunyang-Shuhe highway as an exmple;(5)Contens and purposes critical evaluation of geologic disaster:?Historical activity level of geologic hazards:including scale,frequency, consistency; ?In days to come developing term of geologic hazards:including geologic setting, configuration geomorphy condition, climatic condition, gydrologic condition, vegetation condition, artificial activity ect; (3) Historical activity of geologic hazards ,future occurring probability and danger level of geologic hazards and are assessed;(6)It gains critical evaluation results of geologic hazards' forecast which applys GIS, remote sensing video,database building and AHP ect methods to assess.
