长江南京新济洲河道整治工程与沿岸堤防防洪安全的实践与思考

Practices and thoughts on the river regulation project of Xinji Continent and the costal flood control safety along the Yangtze River in Nanjing

长江南京新济洲河段受上游小黄洲汊道河势变化影响,加之新济洲河段一直未得到系统治理,导致新生洲左、右汊分流比发生变化,造成近岸河床刷深和崩岸险情增加,影响沿岸重要设施安全。通过介绍近期已经实施的新济洲整治工程,结合每年常规的水下地形监测分析工作,总结分析新济洲整治工作的效果,同时提出做好河段内堤防安全工作的建议,为今后长江河道整治工作提供借鉴。

Affected by the change of the river regime of Xiaohuang Continent branch in the upper reaches,and the Xinji Continent section of Yangtze River has not been systematically governanced,resulting in the change of the distributary ratio of the left and right branches of Xinji Continent,resulting in the increase of the near-shore riverbed brush depth and bank collapse risk,and affecting the safety of important coastal facilities.By introducing the Xinji Continent river regulation project which has been implemented recently and combining with the annual routine underwater topography monitoring work,the effect of the Xinji Continent river regulation work was summarized and analyzed.Meanwhile,some suggestions on the safety of embankment in river sections were put forward,which could provide reference for the river regulation work of the Yangtze River in the future.
