Evaluation of Regional Geological Hazards Risks on Kangding to Changdu Section of Sichuan-Tibet Railway
摘要
Abstract
The Kangding to Changdu section of Sichuan-Tibet railway line is characterized by large height difference of terrain, geological hazards of high speed and large scale, and strong tectonic activity. The geological hazards are divided into four grades:(Ⅰ) low-risk;(Ⅱ) medium-risk;( U) high-risk and (Ⅳ) extremely high-risk according to field investigation and analysis. The main geological hazards are classified into collapse-landslides,debris flows and fault fracture zone disaster based on grey cluster theory. The scaling method is employed to construct judgment matrix and the method of analytic hierarchy process ( AHP ) is used to establish regional geological hazards risk model. The model is applied to evaluate regional risks of geological hazards on Kangding to Changdu section. The results show that the hazards mainly fall into high-risk grade on Kangding to Changdu section and design standards should be raised during the construction to better resist the influence of geological hazards.关键词
