| 摘要: |
| 根据对水文泥沙条件及河床演变的分析，选择南港北槽开辟深水航道是合理的。定床和动床模型试验结果表明，用以整治为主、疏浚为辅的方法，取得－１２．５ｍ深水航道是可能的。长江口深水航道工程是对长江口进行综合治理、规划的重要组成部分，在总体上有益无害。 |

| Abstract: |
| Based on local hydrological and sediment data and river bed processes analysis, it is reasonable to select the North passage of South branch as the future deep water channel.Fixed and movable bed m'odel tests show that it is possible to have a-12. 5m deep water channel by means of training works (mainly) and dredying (supplementarily). The project is one the important component parts and the first-step project of the comprehensive training plan for the development of the Yangtze estuary. In general, the project is of much benefit in all aspects. |
