针对散粒体边滩，在对河床演变相关文献的深入分析基础上，通过概化水槽试验重点研究散粒体边滩河床演变规律。由对比分析其演变趋势，得出散粒体边滩演变具有顺水流方向延长的规律，易受扰动发生垮塌现象，并在其下游侧易发生回旋淤积。以此为后续深入探究河床演变机理及类似工况下的排险清淤提供理论依据。
針對散粒體邊灘，在對河床縯變相關文獻的深入分析基礎上，通過概化水槽試驗重點研究散粒體邊灘河床縯變規律。由對比分析其縯變趨勢，得齣散粒體邊灘縯變具有順水流方嚮延長的規律，易受擾動髮生垮塌現象，併在其下遊側易髮生迴鏇淤積。以此為後續深入探究河床縯變機理及類似工況下的排險清淤提供理論依據。

Based on an in-depth analysis of related literature on fluvial process ,this thesis focuses on the trend of bulk solid point bar fluvial process by means of the flume generalization experiment .According to an analysis of the evolution trend ,it is found that the bulk solid point bar evolves by the direction of the water flow .It also leads easily to a collapse by the disturbance and has cyclotron sedimentation on the downstream side .These can provide a theoretical basis for the subsequent study of fluvial process ,danger elimi‐nation and dredging under similar conditions .
