摘要
岩溶塌陷是近年来湘潭市的主要地质灾害,尤其是进入90年代,随着城市的发展,塌陷明显增多,使各种工业与农用设施遭到严重破坏,严重威胁人民生命财产的安全。对潜在塌陷的危险性进行评价是减轻湘潭市岩溶塌陷灾害面临的一个重要问题。现场调查和室内物理模型试验结果表明,岩溶塌陷的产生是受多种因素影响的,这就给岩溶塌陷的预测评价工作带来很大困难,本文以详细的塌陷调查、勘探以及试验资料为基础,运用基于地理信息系统(GIS)的多因素定量评价方法、模型试验方法以及单因素定性分析方法相结合的手段,对湘潭市潜在塌陷危险性进行预测评价,结果表明这不失为一种行之有效的新方法。
In the project of reducing karst collapse losses in Xiangtan, Hunan Province, as a comprehensive method, Karst Collapse Evaluation System was selected to assist government in evaluating karst collapse hazards. It is undoubted that karst collapse is influenced by multiple factors, such as bed rock karstification, the geological structure, the soil properties, the hydraulic conditions, etc.. In this paper, it is discussed in detail the methods to process and combine all of the influential factors from different sources.
