应用遥感与地理信息系统评价公路地质背景的方法

在公路的预设计阶段 ,需要快速、廉价的公路地质背景信息 ,遥感与GIS技术正能满足这种要求。本文认为利用遥感与GIS评价公路地质背景应包括地理因素、地质条件、水文地质与工程地质等因素 ,空间评价应从公路分段评价、重点工程评价、地质灾害分布三方面进行。本文介绍了应用这种方法对贵州省镇兴公路关岭至兴仁段的地质背景评价

THE METHODS TO EVALUATE THE GEOLOGICAL BACKGROUNDS OF HIGHWAYS ON THE BASIS OF GIS AND REMOTE SENSING

The information about geological settings is key to the construction of highways and it is important to study them in detail in the pre\|design period. The paper presents the methods that are based on remote sensing and geographical information system techniques, which can be used to evaluate the geological settings. We hold that such evaluation should include such aspects as geography, geology, hydrological geology and engineering geology. At the end of this paper, an example is given.
