基于GIS与稀疏钻孔数据的岩溶塌陷易发性评价方法研究

An research on evaluation method of liability to karst collapse based on GIS and sparse hole-drilling data

结合使用数据库表文件Excel,以广州市某地区岩溶地面塌陷易发性评价为例,提出了一种基于GIS技术和不均匀钻孔数据的岩溶地面塌陷易发性评价的新方法,得出了与实际情况符合的评价结果,表明该方法计算方法简单易行、实用性强。

With the application of excel,and taking the evaluation of Guangzhou＇s liability to karst collapse as an example,this paper puts forward a practical new method for evaluating liability to karst collapse based on GIS technology and uneven hole-drilling data,and gets an evaluation result identical with the actual situation.The result shows this method is simple and practical.
