摘　　要：结合川江铜鼓滩的整治情况,对山区河流弯曲分汊浅滩水流运动特性、卵石输移运动规律、浅滩碍航特征、整治措施等弯曲分汊类浅滩的整治技术进行研究,归纳出弯曲分汊浅滩治理要点,为弯曲分汊类浅滩的整治工作提供借鉴。The mechanism of forming the gravel shoals on bending braided montain river is complex.Lack of cognition for characteristics of complex rapids and scree running law would exert influence on improvement result.Based on the understanding of Chuanjiang Tonggutan situation,it made a research the governing ways of flow running law,scree moving law,shoal blocking characteristic and regulation technology was carried out.Governing ways of shallow curved branching points were summarized,which provided some reference for improving the situation of bending braided gravel shoals.
