克孜尔水库异重流排沙分析及塑造技术研究

为了探究渭干河克孜尔水库异重流排沙规律,从而提高水库异重流排沙效率,通过对新疆渭干河流域克孜尔水库异重流实测资料的分析,结合已有水库异重流研究成果,对克孜尔水库异重流发生、持续运行及其应用于水库排沙减淤工作的基本规律进行了系统研究,给出了水库异重流排沙的各项物理指标范围。利用水库异重流基本规律及排沙特性,探究了新疆克孜尔水库堤渠结合辅助塑造异重流排沙技术,实践证明此种异重流塑造手段的排沙效果显著,为今后水库利用异重流排沙减淤工作提供了理论基础与实践经验。

Technologies of Desilting by Creating Conditions forDensity Flow in Kizil Reservoir

In order to enhance the desilting efficiency by density flow in reservoir, we conducted systematic research on the formation, running, and application of density flow for the desilting of Kizil Reservoir in Xinjiang, and gave the quantified ranges of physical indicators of density flow. Furthermore, we proposed engineering measures such as combining dyke and canal, and controlling reservoir water level to create conditions for density flow. Practice proved that the proposed measures are of remarkable desilting effect. This research offers theoretical basis and practical experience for the desilting of reservoir by density flow.
