摘要： 三峡水库按175 m方案运行以后,重庆河段的泥沙淤积将成累积性增加,两岸边滩加高加宽,河床演变剧烈,泥沙淤积将会对重庆河段的港口、航道和沿江市政基础设施和生态环境等造成一定负面影响。综合各方面考虑,进一步加大长江上游的水土保持力度,采取建库拦沙及蓄水攻沙,根据泥沙淤积情况规划调整河道岸线,实施港口改造和航道整治等综合措施,将成为减少重庆河段泥沙淤积的有效途径。

Abstract: After the Three Georges Reservoir running according to 175m scheme,it is showed that the deposits will increase accumulatively with the TGR running in the downtown reach,the river bar will be widen and heighten.At the same time,the movement of bed evolution will be acute.The sediment aggregation will bring out certain negative influence on harbor,navigation,the infrastructures and eco-environment along both banks of the reach of Chongqing.Taking various aspects of research achievements into consideration,the main engineering measurements are put forward in order to decrease the influence,such as reinforcing soil conservation,building reservoirs at upstream to prevent sand sedimentation,narrowing the flow to wash sand,implementing bank regulation,harbor reconstruction and navigable channel treatment etc.These measures will be very effective on decreasing deposition and eliminating the negative effects.

Key words: Three Georges Reservoir, sediment deposit, channel regulation, treatment measures
