摘　　要：根据长江中下游有关崩岸实例,结合以往的相关研究,经过归纳总结和分析,从不同角度出发对崩岸进行类型划分,并阐述各种崩岸的形成条件及特征。结果表明:按崩岸外观形态和特征区分,有洗崩、条崩和窝崩3种类型;按崩塌模式区分,有浅层崩塌、平面崩塌、圆弧滑动崩塌与复合式崩塌4种类型;按崩岸成因区分,有侵蚀型、坍塌型、滑移型和迁移(流滑)型4种类型。各类崩岸之间存在一定的内在关系。Riverbank collapses are categorized based on studies of instances of riverbank collapse in the middle and lower reaches of the Yangtze River and previous research and achievements. They can be categorized as wash collapse, strip collapse or are collapse according to their appearances and characteristics; as shallow failure, plane failure, rotational failure or compound failure according to their modes of failure; and as erosion collapse, crash collapse, slide collapse or flow slide according to the collapse formation conditions. The formation conditions and features of each type are also described.
