摘要
讨论了岩溶发育强度分带的现状,提出了岩溶发育强度垂直分带的原则,以钻孔岩溶率、溶洞规模和钻孔涌(漏)水量作为定量指标,以岩组特征、地质构造特征和地下水运动特征作为定性指标,划分为强烈、中等和微弱3个岩溶发育带,并用类比、主因素判别法及模糊综合评判方法确定岩溶发育的强度等级。
The present situation of the intensity zonation of karst development is discussed, and the regulation of the vertical zonation of karst development is proposed. Through taking the karst rate in borehole, the dimension of karst cave and the outflow or leakage water in borehole as quantitative indices, and the feature of stratum, the feature of geoloyical structure and the flow pattern of groundwater as qualitative indices, karst intensity is classified into intensive,mediate and gentle zones,and the intensity grades of karst development are determined by analogism,main factor and fuzzy comprehensive evaluation method.
