Analysis of Beach Protection Project Function in Middle Reaches of the Yangtze River

Abstract:

Beach protection band is the main common type of channel maintenance engineering in the lower-middle reaches of the Yangtze River After the building and water impoundment of three gorges project, the natural condition of water and sediment and evolution law of river channel under the dam beach are changed, the stream wise erosion and regulation will happen by long distance and periods. Through field investigation, data analysis, theoretical research and other means, the impact of beach protection structure under clear water scour are studied; the characteristics and applicable conditions of beach protection zone are also studied. The applicable conditions depend on engineering goals, A new understanding for beach protection engineering transformed from the defensive to offensive function are put forward, which provides control ideas and principles for the implementation of the follow-up project.
