摘要
应用地理信息系统具有的定性、定量、定位分析功能进行九龙—石棉500 kV送电线路的优选工作。首先根据工作区特点,建立工作区评价指标体系,对影响线路优选的各类指标进行数字化和栅格化,得到评价指标图层,再利用GIS进行叠加运算,初步选定南、中、北三个方案,对条件较优的南方案进行缓冲分析,然后生成南方案走廊带,进行多要素分析,形成工程地质分区,对工程地质条件较复杂的区域进行局部方案比选,推荐条件较优的路径。
Geographic information systems have qualitative and quantitative and positioning analysis of function, thus it is used to do optimal selection of 500 kV transmission line from Jiulong to Shimian. All kinds of assessment index, and transform assessment index are digitalized to grid layers according to working area characteristics to establish assessment index system. The paper used GIS to do overlay analysis, and initially got South Middle and North program. By contrasting the South program is considered as better choice. By doing buffer analysis of shape aisle of transmission line, the best transmission line are recommended.
