调查区内地形、地貌、地质构造、地层岩性和社会经济条件与输电走廊的建设和运行紧密相关。为综合评价输电走廊的合理性以及送电线路施工服务的便利性,采用遥感和地理信息系统技术调查走廊带工程地质环境。结合野外调查,通过室内遥感解译,判别地质灾害基本特征,建立滑坡泥石流预警预报模式。
The topography, geomorphology, geological structure, stratigraphic lithology and socio-economic conditions in the survey area are closely related to the construction and operation of the transmission corridor. In order to comprehensively evaluate the rationality of transmission corridors and the convenience of construction services of transmission lines, remote sensing and geographic information system (GIS) techniques are used to investigate the corridor environment. Combined with the field investigation, through the interpretation of indoor remote sensing, discriminate the basic characteristics of geological disasters and establish the landslide debris flow forecasting and forecasting model.
