Abstract:Due to high development intensity of port and waterway resources in the Yangtze River estuary, the generated quantity of dredged materials is large, and dredged materials’ disposal has become a major technical problem in the field of port and waterway engineering. Using lots of engineering field data, we analyze the source, quantity and properties of dredged material of Yangtze Estuary, summarize the current situation and main problems, and discuss the future outlets of dredged materials generated from the Yangtze estuary. The results show that the annual average quantity of dredged materials is nearly 100 million square meters, which is generated mainly from the 12.5-meter-deep waterway of the South Channel and North Passage of the Yangtze estuary and secondary channel of Waigaoqiao port area phase four to six project of Shanghai port. At the present stage, the dredged materials are still mainly dumped to ocean dumping sites, the ratio of resource utilization is not high generally, and its use pattern is relatively simple. Under the background of more stringent ocean dumping management and more popular lowcarbon circular economy, the fundamental outlet of dredged material disposal of Yangtze estuary lies in higher level of multiply resource utilization, effective engineering measures for port and waterway sedimentation reduction, and strengthening assessment and rational use of ocean dumping sites.
