中文摘要:
      输变电线路工程往往具有跨区域广、沿线地形地质条件极为复杂、各种自然灾害频发、灾害风险高等特点。本文首先通过对山东淄博市输变电工程沿线的水土流失次生灾害调查,分析研究了沿线灾害发育的规律及特征,其灾害发育主要受地形地貌、地层岩性、降雨控制。随后选择了高程、坡度、坡向、地貌类型、降雨、断层距离、土地利用类型、水系密度、岩性、道路距离、矿区距离共11个因子作为评价指标,融合层次分析法和信息量法对研究区的灾害危险性进行了评价,成功率曲线AUC为0.76,显示评价精度较高。评价结果表明:沿线杆塔位于极低危险区3151个,位于低危险区1696个,位于中危险区2622个,位于高危险区1011个,位于极高危险区71个。同时危险性区划图可以为输变电工程的选线、灾害防治等提供科学依据,具有重要的应用价值。
英文摘要:
      Transmission and transformation line projects often span a wide range of regions, with extremely complex topographical and geological conditions along the line, frequent natural disasters and high disaster risk. Firstly, through the investigation of the secondary disasters of soil and water loss along the power transmission and transformation project in Zibo City, Shandong Province, the laws and characteristics of the development of disasters along the line are analyzed and studied. Their development is mainly controlled by topography, formation lithology and rainfall. Then 11 factors such as elevation, slope, aspect, geomorphic type, rainfall, fault distance, land use type, water system density, lithology, road distance and mining area distance are selected as the evaluation indicators. The disaster risk of the study area is evaluated by integrating the analytic hierarchy process and the information quantity method. The success rate curve AUC is 0.76, and the evaluation accuracy is high. The evaluation results show that the towers along the line are located in 3151 extremely low risk areas, 1696 low risk areas, 2622 medium risk areas, 1011 high risk areas and 71 extremely high risk areas. At the same time, the hazard zoning map can provide scientific basis for route selection and disaster prevention of power transmission and transformation projects, and has important application value.
