摘　　要：水电工程水库影响区包括水库滑坡、变形库岸、塌岸、浸没、岩溶内涝和采空变形影响区等6类,相关规范对其判别原则与判别工作内容进行了规定,但鉴于地质条件复杂性和影响对象多样性,水库影响区判别地质工作中尚有一些认识有待统一。在多座大型水电站水库影响区判别实践经验的基础上,重点对水库滑坡、变形库岸、塌岸、浸没影响区判别中的要点进行了实例分析,并结合部分工程实例,对现有影响区类型之外的一些特殊水库影响型式如水库内涝影响区、水库泥石流影响的判定进行了阐述。The impoundment-affected area of hydropower engineering comprises landslide,deformed reservoir bank,bank collapse,submergence,karst inundation,and mining subsidence deformation impact areas.Related standards have specified the principles and the contents for identifying impoundment-affected area,but in view of the complexity of geological conditions and the diversity of affected objects,some knowledge yet to be unified.Based on the practical experiences of many large-scale hydropower stations,this paper focuses on the key points for identifying such impoundment-affected areas as landslides,deformed reservoir bank,bank collapse and submergence impact area,and combines some engineering examples to elaborate on the determination of two special types of impoundment-affected area,that is reservoir inundation impact area and reservoir debris flow impact.
