| 中文摘要: |
| 沙坪河与郁江交汇口的夹角较小，不利于船舶转弯航行，特别是郁江上游进出沙坪河的船舶转弯困难；此外，在交汇口航道右岸岛屿上分布着大量居民房，征地、拆迁较为困难。如何统筹兼顾航行条件与少征地、少开挖是该河段航道线路布置的难点。为使船舶在运河航道中的适航性和安全性达到良好，按照直线为主、弯道为辅的原则布置2条航道线路。经技术经济比较，选择航行安全、施工难度小、工程造价低的航道线路，并选择代表船型、建立电子航道图对该航道线路进行船舶操纵仿真试验。船模试验表明，优化设计方案的航道宽度及转弯半径均满足通航安全的要求。 |

| The angle of the confluence of Shaping River and Yu River is small,which is unfavourable for ships to turn and navigate,especially for ships entering and leaving Shaping River from the upper reaches of Yu River.In addition,a large number of residential houses are distributed on the islands on the right bank of the channel at the confluence,which makes land acquisition and demolition difficult.How to balance the navigation conditions with less land acquisition and less excavation is a difficult point in the channel route layout of this section.To achieve good seaworthiness and safety of ships in the canal channel,two channel routes are arranged according to the principle of straight line as the main and curve as the auxiliary.Through the comparison of technology and economy,the channel line with safe navigation,low construction difficulty and low engineering cost is selected.Furthermore,the representative ship type is selected and electronic channel chart is established for the ship manoeuvring simulation test.The ship model test shows that the channel width and turning radius of the optimised design meet the requirements of navigational safety. |
