横沙东滩促淤圈围（七期）工程位于长江口北槽北导堤的北侧，紧邻长江口北槽深水航道，且处于航道维护困难段，工程建设后，附近水域水动力条件和河床冲淤发生变化，对北槽深水航道维护带来一定影响。文章通过建立三维潮流、泥沙数学模型，计算分析工程建设对北槽深水航道的影响。经过验证，计算结果与实测数据吻合，分析结果可靠。
橫沙東灘促淤圈圍（七期）工程位于長江口北槽北導隄的北側，緊鄰長江口北槽深水航道，且處于航道維護睏難段，工程建設後，附近水域水動力條件和河床遲淤髮生變化，對北槽深水航道維護帶來一定影響。文章通過建立三維潮流、泥沙數學模型，計算分析工程建設對北槽深水航道的影響。經過驗證，計算結果與實測數據吻閤，分析結果可靠。

The Hengsha east shoal siltation and reclamation project (Phase 7) is located on the north of the north jetty in the Yangtze estuary north passage, and close to the Yangtze estuary deepwater channel, which is the most difficult part of the channel maintenance. The project construction will change the current dynamics and riverbed scour and deposition, then will influence the north passage maintenance. We used a 3-D tidal-sediment model and sediment numerical model to analyze the influence of the project construction on north passage of Yangtze estuary deepwater channel. After verification, the calculation coincides with the measured data, the results of the analysis is reliable.
