乌鲁瓦提水库排沙影响因素研究

Influencing Factors of Sediment Delivery of Wuluwati Reservoir

乌鲁瓦提水库自建库以来未开展过系统的水沙特性及排沙影响因素研究。为分析水库排沙规律,笔者通过分析实测资料建立水文站水沙关系,对水库入库水沙过程、水库排沙运用情况进行了统计分析,并根据库区实测地形分析了水库淤积现状及淤积分布特征,研究了水库排沙影响因素,采用回归分析法建立了排沙比计算公式,可为近期水库排沙调度方案的制定提供参考。

Since the establishment of Wuluwati Reservoir,no systematic study has been carried out on the characteristics of water and sediment and the influencing factors of sediment delivery.In order to analyze the law of reservoir sediment delivery,the water-sediment relationship of hydrological station is established by analyzing the measured data,and the process of reservoir inflow water and sediment and the application of reservoir sediment delivery are statistically analyzed.According to the measured terrain of the reservoir area,the status and distribution characteristics of reservoir sedimentation are analyzed,and the influencing factors of reservoir sediment delivery are studied.The regression analysis method is used to establish the calculation formula of sediment delivery ratio,which can provide reference for the formulation of reservoir sediment delivery scheduling scheme in the near future.
