向家坝非恒定流对航道通航条件影响的试验研究

非恒定流对下游河道通航条件影响是向家坝工程实施时需要考虑的主要问题。传统的通航条件影响研究,不能全面准确反映航道水流条件和边界条件对船舶航行的综合影响以及船舶与航道水流条件的相互作用。利用小比尺船模测控技术,通过与实船相似性分析和操纵性能率定,试验研究向家坝非恒定流对下游河道通航条件的影响,结合试验研究成果定量分析主要影响因素,为向家坝工程方案的设计优化提供了科学可靠的数据基础。

Test research of influence of Xiangjiaba unsteady flow on downstream channel navigation condition

Influence of unsteady flow on navigation condition of downstream channel is the main issues to consider in the implementation of Xiangjiaba project. Effects of water flow conditions and boundary conditions on the ship navigation and the interaction between the ship and the channel cannot be fully and accurately reflected in traditional study on the influence of navigation conditions.Using measurement and control technology of small scale ship model,based on similar analysis and maneuverability calibration of real ship,we research the influence of unsteady flow on navigation condition of downstream channel.Combined with experimental results,the main influence factors are quantitatively analyzed,which provide scientific and reliable data basis for the optimization design of the Xiangjiaba project.
