宁东能源化工基地供水工程鸭子荡水库黄河取水泥沙分析研究

Analysis and Study on Water Intake Sediment from Yellow River in Yazidang Reservoir,Water Supply Project of Ningdong Energy and Chemical Industry Base

鸭子荡水库是宁东能源化工基地的命脉工程,承担着为基地工业、生态、生活安全、可靠供水的大任,其安全与正常运行关系着宁东乃至宁夏经济的健康高质量发展。由于工程水源为黄河水,其含沙量及变幅均较大,因此,文章研究了鸭子荡水库黄河取水泥沙问题,分析了入库泥沙的规律及输沙量,为鸭子荡水库安全可靠运行及二期扩容加坝及类似黄河取水工程取水泥沙的选取提供了技术指导及借鉴,意义重大。

Yazidang Reservoir is the lifeblood project of Ningdong Energy and Chemical Industry Base,which undertakes the responsibility of safety and reliable water supply for industrial,ecological and life of the base.Its safety and normal operation are related to the healthy and high-quality development of economy in Ningdong and even Ningxia.Because the project water source is the Yellow River,the sediment concentration and amplitude are higher.Therefore,the water intake sediment from Yellow River in Yazidang Reservoir is studied in the paper.The law of incoming sediment and sediment discharge are analyzed,thereby providing technical guidance and reference for selection of safety reliable operation in Yazidang Reservoir,stage II capacity expansion and dam heightening project,similar water intake sediment like the Yellow River.It has great significance.
