摘　　要：论述了非冲积性滩险类型、基本成因、滩险碍航特点、水流特性及其分析方法。通过滩性分析可以确定滩险成滩水位、最凶水位、消滩水位(流量)的成滩出现时期及滩段凶、险的定量概念。结合滩段地貌、地形特点,确定碍航水流具体成因,并据以制定整治原则和方法。The type,forming reason,specific property of obstacle to navigation,flow characteristics of rock rapids and their method of analysis are discussed.Based on the analyis of rapids characteristics,the rapids-forming stage,the most turbulent stage in the rapids-forming period are determined.According to the forming of obstacle to navigation,characteristics of the bed configuration and the bed,geomorphic/geology,the principle and measure regulation work are worked out.
