Risk Zoning of Hazards along Highways to Xizang Based on Information Model
摘要
Abstract
The frequent occurrence of hazards along the highways in the Qinghai-Xizang Plateau seriously affects road traffic and threatens the security of lives and property of the people.Conducting a risk zoning assessment of hazards along the highways to Xizang is crucial to enhancing hazard prevention and mitigation.This paper summarized the regional geological environment and development patterns of hazards along the highways to Xizang and analyzed the overall performance of highway traffic operations.On this basis,the Xinjiang-Xizang Highway was taken as the research object,and the evaluation factors were selected based on the regional geological environment and the main controlling factors of meteorological hazards.By using an information model based on multi-source data fusion,a risk assessment model was established for flood hazards,geological hazards,and comprehensive hazards along the Xinjiang-Xizang Highway.The information value of different evaluation factors was obtained,and the susceptibility maps for flood hazards and geological hazards,a risk zoning map,and a comprehensive hazard risk zoning map were drawn.The results show that high and extremely high-risk zones for geological hazards contain 96.09%of the known geological hazard risk points,and the high and extremely high-risk zones for flood hazards include 94.74%of the known flood hazard risk points.The comprehensive hazard risk zoning map shows that the high and extremely high-risk zones contain 95.76%of the known hazard risk points.These maps demonstrate the actual hazard risks along the highways to Xizang,validating the effectiveness of the proposed method.关键词
