基于3D实景模型和AHP边坡危险性评价系统的应用:以沿黄公路吴堡-永和段为例
Application of Geological Hazard Risk Assessment System Based on 3D Real Scene and AHP:Example from the Wubu-Yonghe Section along the Yellow River Highway
摘要
Abstract
In order to effectively control,manage and reduce the adverse effects of highway slope geological disasters,this study proposes a new method of highway slope risk assessment based on UAV tilt photography and three-dimensional real scene slope information extraction combined with analytic hierarchy process,and de-velops a three-dimensional visualization web platform for highway slope risk assessment along the Yellow Riv-er Based on cesium.The three-dimensional real scene model and computer algorithm can be used to extract the slope risk evaluation information(including road slope distance,slope,slope height and joint density,etc.)in the room.The AHP is used to evaluate the risk of each slope.According to the comprehensive final risk score,it is divided into five risk levels:extremely low,low,medium,high and extremely high.The proposed method is ap-plied to the risk assessment of slopes along the Yellow River Highway.A total of 656 slopes are evaluated,in-cluding 0 extremely low-risk slope,23 low-risk slope,405 medium risk slope,210 high-risk slope and 18 ex-tremely high-risk slope.The evaluation results are consistent with the field survey results,which show that the evaluation system proposed in this paper is effective and reasonable.The system not only realizes the three-di-mensional visualization investigation and risk assessment of geological disasters,but also promotes the develop-ment of digital and intelligent application of highway slope disaster prevention and reduction technology.关键词
