南汇东滩促淤圈围工程位于上海市长江口南岸下段南槽右侧边滩,隔南槽航道与九段沙国家生态保护区相望;上接浦东国际机场,下临上海临港新城。工程圈围造地顺岸长约22km,离岸深入河口江中约2.5~5.4km,共建促淤堤49.6km,圈围防洪大堤46km,成陆吹填土方约6000万m~3,造地面积约11.6万亩。南汇东滩促淤圈围工程是国内已实施的在淤泥质软土海岸带造地规模最大的工程,其中一、二期促淤,三~五期圈围成陆。针对工程特点和难点,设计综合运用多种先进手段,因地制
The project of promoting sedimentation and sedimentation in Nanhui Dongtan is located on the right side beach of the south bank of the south bank of the Changjiang Estuary in Shanghai. The South Gap Channel is across from the Jiuduansha National Ecological Protection Zone. It is connected to Pudong International Airport and next to Shanghai Lingang New City. The surrounding area of the project is about 22km long along the coast and about 2.5 ~ 5.4km away from the estuary in the estuary. The total length of the embankment is 49.6km, the flood control embankment is 46km, the landfill fill is about 60 million m ~ 3, Land area of about 116,000 mu. The project of promoting sedimentation and silting in Nanhui Dongtan is the largest project in the country that has been implemented on the muddy soft soil coastal zone. Among them, the first and second phases are silting up and the third to fifth phases enclose land. For engineering features and difficulties, the design of integrated use of a variety of advanced means, due to the system
