大顶子山航电枢纽河段现状条件下河床演变规律

Fluvial processes of the section of Dadingzishan Hydro-junction

以实测水文、泥沙及地形资料为依据,分析了枢纽河段来水来沙特征及现状条件下河床演变规律,并结合定床试验成果、库区泥沙数学模型及枢纽运用方式,预估了枢纽河段泥沙输移规律。

Based on the measured data of hydrology, sediment and geomorphology, flow and sediment characteristics and flurial processes of the river section of Dadingzishan Hydro-junction is analyzed. And the pattern of sediment transport of the river section is estimated from fixed bed model test result,math model of the reservoir area and operation mode of the junction.
