基于多源遥感数据的1000 kV山东环网特高压线路地质灾害风险评价
|
摘要
山东环网全称为潍坊—临沂—枣庄—菏泽—石家庄1000 kV特高压交流输电线路工程。以山东环网3标段沿线为研究区,收集和整理现有资料,选取坡度、坡高、坡向、坡形、距离水系距离等5个具有代表性的因素作为滑坡地质灾害的评价因子,通过层次分析法,对各个评价因子赋予权重。运用ArcGIS10的邻域分析、提取分析、表面分析、距离分析、重分类、加权叠加、重采样等工具,对各评价因子的多源遥感数据进行区域性分析,获得研究区的地质灾害风险评价图。对此区域进行地质灾害风险评价,将此区域内的地质灾害风险等级划分为:低风险、中等风险、高风险、极高风险4类。选取各类风险点与野外勘查结果进行对比,所得结果与野外调查结果基本一致。
Shandong ring network is called Weifang-Linyi-Zaozhuang-Heze-Shijiazhuang 1000 kV ultra-high voltage alternating current transmission line project.Based on the research area along the standard section 3 of Shandong ring network,the existing data are collected and sorted out.Five representative factors such as slope,slope height,slope direction,slope shape and distance from water system are selected as evaluation factors of geological hazards,Each evaluation factor is weighted by analytic hierarchy process(AHP).The remote sensing data of each evaluation factor were analyzed by means of neighborhood analysis,extraction analysis,surface analysis,distance analysis,reclassification,weighted superposition,resample and other tools of ArcGIS10 to obtain the geological disaster risk assessment map of the study area.The risk level of geological disaster in this region is divided into four categories: low risk,medium risk,high risk and very high risk.All kinds of risk points were selected and compared with the results of field survey,and the results were basically consistent with the results of field survey.This paper introduces the combination of analytic hierarchy process(AHP) and multi-source remote sensing data to provide reference for analyzing and evaluating engineering geological hazard risk of ultra-high voltage alternating current transmission lines.
