摘　　要：根据常见的构造地貌及岩溶-构造-地貌内在动力联系特征,系统地将西南山区分为5种常见的岩溶水文地质结构类型(平顶山型、单斜山型、褶曲山型、断块山型和褶断山型)以及多个亚类型,并探讨各结构类型的地下水动力特征和各类型常见的涌突水部位,简单分析了各类型的岩溶危害程度。这些结构类型的构建和提出,为山岳岩溶隧道涌突水预测评价提供了重要的地质概化模型。According to common structural geomorphology and karst-structure-geomorphic intrinsic dynamic connection,the southwest mountainous area is systematically divided into five common karst hydrogeological structure types(flat-topped,monoclinic mountain type,fold mountain type,fault block mountain type and fold fault mountain type),as well as multiple subtypes and the dynamic characteristics of groundwater of each structure type and common types of gushing and water inrush locations are explored and the degree of karst damage with different types is simply analyzed.The construction and proposal of these types of structures provide an important geological generalization model for the prediction and evaluation of gushing and water inrush in mountain karst tunnels.
