摘　　要：为有效防治水电水利工程建设和营运过程中可能遭遇的水文地质问题,本文以岩体工程地质力学理论为指导,在已有国内外岩体结构、水文地质结构认识的基础上,提出了深切河谷水文地质结构的概念。针对中国水电工程建设的主战场——西部深切河谷区地质环境特征,总结归纳出岸坡型、顺河型、跨河型、区域型4大类深切河谷水文地质结构及其特征表现,并初步阐述了各类河谷水文地质结构对相应水电工程建设项目工程水文地质问题的控制机理。This paper proposes the concept of hydrogeological structure of deep-incised river valleys.It aims to effectively prevent and control the hydrogeological problems that may be encountered in the construction and operation of water conservancy and hydropower projects.The proposal of this concept is guided by the theory of rock engineering geomechanics and is based on the understanding of rock mass structure and hydrogeological structure.In China,most of the hydropower projects are built in deep-incised river valleys in western areas.With regard to the geological and environmental features in the areas,this paper summarizes four types of deep-incised river valleys including bank slope type,river-paralleling type,river-crossing type and regional type.It also summarizes their corresponding characteristics.In addition,this paper also preliminarily expounds the control mechanism of these types of valleys on the engineering hydrogeological problems during the construction of hydropower projects.
