上海岸带冲淤及对深水航道工程的影响

Shanghai Coastal Erosion and Accumulation and Its Influence on Deep-water Channel project

长江入海泥沙在复杂的河口地貌和水动力条件下,自然岸带的冲淤频繁多变,给沿海重大工程带来不利影响,成为上海地区重要的地质灾害种类。本文结合长江河口地区泥沙运移监测成果,分析了其对长江口深水航道工程的影响,为工程的日常维护与安全运行提供借鉴。

The sedimentation of the Yangtze River,under the complex landform and hydrodynamic conditions,have such characteristics as frequent natural erosion and deposition of the coast with changeable,detrimental to major coastal engineering,and become an important kind of geological disaster in the Shanghai area.Based on the monitoring results of the Yangtze River estuary sediments,this paper analyzes its influence on the Yangtze estuary deepwater channel project,which will provide some suggestion for daily maintenance and safe operation of the project.
