摘要
This study investigates the effects of classifying dredged dam sediments on their transport properties. Using a small recirculating flume, experiments were conducted to analyze the erosion and breakdown of placed sediment models composed of silica sand, non-plastic silt, and kaolin. Various mixing ratios were tested, focusing on the influence of fine content ratio (Fc) and clay content ratio (Cc). Results indicate that the erosion resistance of placed sediment models is significantly affected by the clay content ratio (Cc), with higher ratios leading to increased resistance. Additionally, sediment classification and placement methods were explored, revealing that horizontally layered configurations, with sand in the lower layer and clay in the upper layer, increased erodibility. These findings suggest that proper classification and placement of dredged dam sediments can enhance their transport and utilization downstream, addressing issues of riverbed degradation and coastal erosion. Future research should focus on long-term sediment consolidation and full-scale effectiveness evaluations.
