铁路给水水源的勘测,目的在于选择理想的水源,保证足够的储量、方便于车站和工厂的供水。多年以来,铁路部门在工点水文地质勘探中,因受勘探范围和其它条件的限制,工作比较被动。国外引进的地球资源卫星象片的用途是颇为广泛的。探讨它在铁路给水工点水文地质勘探中的应用,这是一项具有实践意义的工作。 The purpose of railway water supply survey is to select the ideal water source, ensure sufficient reserves and facilitate the water supply at the stations and factories. Over the years, the railway department has been passive in worksite hydrogeological exploration due to the limitation of exploration scope and other conditions. The use of satellite images of Earth resources imported from abroad is quite extensive. It is a practical work to discuss its application in hydrogeological exploration of railway waterworks.
