Evaluation of Pipeline Geological Hazard Susceptibility Based on Entropy Weight Method and Information Model
Pipeline geological hazard susceptibility evaluation is the basis of pipeline geological hazard risk control.In order to explore and establish a quantitative evaluation model for pipeline geological hazard susceptibility,this paper takes Qianjiang-Shaoguan Pipeline(Guangdong Section)as an example,and selects evaluation factors such as slope,slope direction,horizontal(profile)curvature,rock and soil properties and geological structure on the basis of field geological environment conditions and geological hazard investigation,and conducts geological hazard susceptibility evaluation zoning based on entropy weight method and information method.Divided into high,medium and low prone areas.The evaluation results provide a basis for pipeline geological disaster risk management and control,and provide a reference for other similar evaluation.
