在公路选线中 ,遥感 (RS)和地理信息系统 (GIS)技术能全面宏观地分析工程区的地质背景及其对整个工程的影响 ,对于降低工程成本及评价未来公路运行的风险具有重要意义。以地处喀斯特山区的贵州省关岭至兴仁二级公路为例 ,应用 RS和 GIS技术对工程区进行了地质背景评价 ,认为公路的设计线路是可行的。同时 ,指出喀斯特山区公路建设的最大隐患是富水断裂带可能发生的岩溶渗水和崩塌 ,应予高度重视
In highway route selection, remote sensing (RS) and geographic information system (GIS) technology can comprehensively and macroscopically analyze the geological background of the project area and its impact on the whole project, which is of great significance for reducing the project cost and evaluating the risk of future road operation . Taking the Guanling-Xingren Grade-2 Highway in Guizhou Province, located in the Karst mountains, as an example, the geological background of the project area was evaluated using RS and GIS technologies, and the design of the highway was feasible. At the same time, it is pointed out that the biggest hidden danger of highway construction in Karst mountains is the possible karst water seepage and collapse in the Fushui fault zone, which should be highly valued
