RS和GIS支持的喀斯特山区公路建设可行性研究

Study on the Highway Feasibility of Karst Mountainous Area Based on RS and GIS

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 。

During selecting the routes, the application of RS and GIS is very significant to reduce the cost of project and forecast the future hidden trouble. In the case study of Guanling——Xingren highway in the Karst mountain area, the authors apply RS and GIS to evaluate the geological condition and feasibility of the project. The result confirms that the design of highway is feasible. The study indicates that we should pay attention to the enriched-water fault that is the greatest hidden trouble during the construction of highway in the Karst mountain area.
