涪江吴家渡电航工程船模通航试验研究

Research on ship model experiment of Wujiadu hydroelectric power project of Fujiang River

采用自航小尺度船模技术,通过水工模型对吴家渡电航工程的通航条件进行了研究。试验结果表明,当Q≤3000m3/s时,该枢纽工程的通航条件满足Ⅴ级航道通航标准。试验发现,船队的航线和驾驶方式以及枢纽的运行方式对航行安全都有很大影响。建议枢纽建成后,通过设置航标等方法确保过往船舶顺利通航。

Based on the technology of small-scale self-propelled ship model,the navigation conditions of Wujiadu hydroelectric power project were studied by the hydraulic model.The test results show that the channel navigation conditions of the hydro-junction can meet with the grade V navigation standard when the discharge is less than or equal to 3 000 m^3/s.The experimental results indicate that fleet route,driving pattern and hydrojunction operation mode have a great influence on the safety of navigation.It is suggested that navigation marks establishment and other methods should be carried out to ensure the navigation of ships after the construction of Wujiadu hydro-junction.
