摘　　要：黄土高原地区水流含沙量大,水库运行过程中,上游支流及流域的泥沙不断汇入水库,随着水库运行年限的增加,水库泥沙淤积逐渐增加,影响水库调蓄能力,需开展水库清淤,恢复水库库容,保障水库效益正常发挥。以黄土高原地区巴家咀水库为例,对近年来的入库泥沙进行调研分析,发现库区泥沙淤积严重,须进行水库清淤。因此,结合水库周边环境、城市防护要求、施工条件、工期、清淤费用等多种影响因素拟定了三种清淤方案,进行综合对比分析,选取在工期、经济等方面最优的清淤方案进行水库清淤。The sediment concentration of water flow in the Loess Plateau is high.During the reservoir op-eration,the sediment from upstream tributaries and watersheds continuously flows into the reservoir.As the operating year of reservoir increases,the sediment accumulation gradually increases,which affects the storage capacity of reservoir.It is necessary to carry out reservoir dredging to restore the reservoir ca-pacity and ensure the normal performance of reservoir benefits.Taking Bajiazui reservoir in the Loess Plateau as an example,the sediment inflow in recent years is investigated and analyzed,and it is found that the reservoir area is severely silted and requires dredging.Therefore,based on various influencing factors such as the surrounding environment of reservoir,urban protection requirements,construction conditions,construction period and dredging costs,three dredging schemes are formulated,and compre-hensive comparison and analysis are conducted to select the optimal dredging scheme in terms of con-struction period and economy.
