对三峡水利枢纽坝前漂污物的运移特性、分布规律及其影响因素及治理漂污的工程措施进行了研究。研究表明 :库区漂污物的分布及其运移规律与库区河势、水流流态、库水位、来流量及三峡电站的调度方式等因素有关。在各级水位、流量条件下 ,坝前漂污滞留量分布的基本态势为“右多左少”。通过调度运行 ,可以改变漂污物在坝前的分布情况 ,但基本态势不变。三峡枢纽库区漂污治理 ,应采取“以捞为主”的思路 ,以根本解决三峡及葛洲坝两大枢纽的漂污问题。研究发现 :在坝前及坝区河段可以选择到较为理想的地段和区域建立滞漂、捞漂区 ,导漂、拦漂效果较好 The transport characteristics, distribution and influencing factors of floating sewage in front of the dam of Three Gorges Project and the engineering measures to control bleaching were studied. The results show that the distribution of floating pollutants in the reservoir area and its migration are related to the river regime in the reservoir area, water flow pattern, reservoir water level, incoming flow rate and the dispatching mode of the Three Gorges Power Station. At all levels of water level and flow conditions, the basic trend of the distribution of suspended sludge retention in front of the dam is “right more left than less.” By scheduling operation, you can change the distribution of floating dirt in front of the dam, but the basic situation remains unchanged. Floating pollution control in the Three Gorges Reservoir Area should take the idea of ​​“taking fishing as the mainstay” so as to fundamentally solve the problem of floating pollution at the two major hubs of the Three Gorges and Gezhouba Dam. The study found that: in the dam and the dam area can choose to the more desirable areas and regions to build drift drift, drift drift area, drifting, drift better effect
