摘要
以四川华能瓦斯河流域梯级滚动开发二期工程220 kV送电线路遥感工程地质调查为例,介绍了遥感技术的应用情况。以TM743+SPOT2融合图像为主要信息源,对送电线路走廊进行工程地质遥感解译,以较少的投入,快速、准确、高效地查明研究区的地形地貌、地层岩性、地质构造、岩土体类型、不良地质现象、工程地质条件、植被覆盖等,在此基础上进行工程地质分区,为送电线路的设计提供工程地质依据。
Taking the case of remote sensing analysis and engineering geological survey of 220 kV circuit sent with second period project of Sichuan Huaneng Wasi River basin, remote sensing technology is introduced and employed, and ascertained landform, formation litho logy, geologic structure, the rock, land types, adverse geologic phenomena, engineering geological conditions, vegetation coverage etc. in belt line corridor economically and accurately based on TM743＋SPOT2 image fusion which is as the main source of information. At last, engineering geological division is made in the research area to provide the basis for the lines evaluation design of power transmission.
