摘　　要：长江中游戴家洲河段在实施护岸工程前,戴家洲右缘持续发生崩岸。文章结合戴家洲右缘崩岸情况,从地质、地形、水流条件等角度分析了该处发生崩岸的原因。采用稳定岸坡作为崩岸发生的临界判别指标,基于三峡蓄水前后戴家洲右汊典型断面多年实测资料,得到了戴家洲右缘稳定岸坡值。The bank collapse happens continuously in the right edge of Daijiazhou reach in Middle YangtzeRiver before revetment engineering existing. The cause of bank collapse in the right edge of Daijiazhou was studiedconsidering geology, topography and hydrological process. Considering the stable slope as the critical one, the valueof the right edge of Daijiazhou was obtained by measured typical sections of the right branch of Daijiazhou reach before and after the Three Gorges Reservoir impounding.
