摘要
为查明武汉地区岩溶发育特征,通过对大量揭露碳酸盐岩的工程钻孔进行统计分析,划定了武汉市都市发展区不同时代碳酸盐岩的分布范围,分析了岩溶发育特征,提出延米线岩溶率的概念划分了垂向上岩溶发育的强弱程度分区,探讨了岩溶发育的影响因素。得出了武汉地区距离灰岩顶板埋深1 m^4 m的深度范围是强烈岩溶活动区、4 m^10 m是中等岩溶活动区、10 m以下是弱岩溶活动区的结论。
In order to ascertain the characteristics of karst development in Wuhan area,the distribution range of carbonate rocks in Wuhan urban development area was delineated by statistical analysis of engineering drilling of large number of exposed carbonate rocks,and the characteristics of karst development were analyzed. The concept of line karst rate divides the degree of karst development in the vertical direction,and discusses the influencing factors of karst development. The results is Wuhan area from the limestone roof depth of 1m to 4m depth range is a strong karst activity area,4m to 10 m is a medium karst active area,10 m below is a weak karst activity area.
