白河堡水库泥沙淤积综合治理研究

Study on comprehensive control of sedimentation in Bai - He - Pu Reservoir

白河堡水库泥沙淤积已对输水洞输水造成严重影响,淤积治理已刻不容缓。项目在对淤积状况进行现场查勘、流域调研、资料分析及实体模型试验和数学模型计算基础上,以物模与数模相结合方式进行研究。在此研究基础上提出高水位运行、导沙堤、清淤制砖、筑坝排沙等近远期综合治理方案。

Sediment deposition in Bai - He - Pu Reservoir has exerted a serious impact on water - sediment conduit. It is urgent to control this sedimentation issue. In this project, study on sedimentation was carried out through in - site survey, valley observa-tion, data assimilation, laboratory experiments and numerical modelling. In the paper, a proposal of a comprehensive measure-ment is put forward, such as high stage operation, sediment diversion, dredge and brick - making, dam and sediment flushing. This measure, based on study on sedimentation, will produce short - and long - term engineering benefits.
