摘　　要：为更好地解决北京市南水北调大宁调蓄水库遭受“23·7”流域性特大洪水形成的水库淤积问题,参照大宁调蓄水库清淤方案,进行入库淤积勘察,分析洪水入库对水库影响,比选现有库区清淤方式。结果表明:环保生态清淤方式对土质适应性、施工效率、周边环境、二次污染和水生态保护的影响均比其他方式小,且造价中等;同时避免了库区排水,节约了大量水资源,降低了能耗,减少了对库区生态的干扰。研究成果可为该类水库清淤工程提供新思路。To address the issue of sedimentation caused by the"23.7"catastrophic flood in the Daning Reservoir of South-to-North Water Diversion Project in Beijing area,a dredging scheme for the reservoir was investigated.The impact of flood inflow on the reservoir was analyzed through the analysis of sedi-ment deposition situation.A comparative analysis of existing dredging methods in the reservoir area was conducted.Results indicated that the environmental ecological dredging method exhibited better adapt-ability in terms of soil quality,construction efficiency,impact on the surrounding environment,secondary pollution risks,and effects on water ecological preservation compared to other methods,which also pre-sented with a moderate cost.This method conserved significant water resources,reduced energy consump-tion,and minimized disruption to the ecological environment of the reservoir through the approach of avoiding drainage in the storage area.These findings of this research will offer innovative insights for simi-lar reservoir dredging projects.
