【摘要】：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。
[Abstract]:The influence of unsteady flow on the navigable condition of downstream river is the main problem to be considered in the implementation of Xiangjiaba project. The traditional study on the influence of navigation conditions can not fully and accurately reflect the comprehensive influence of waterway flow conditions and boundary conditions on ship navigation and the interaction between ship and waterway flow conditions. By using the small scale ship model measurement and control technology, the influence of the unsteady flow of Xiangjiaba on the navigation conditions of the downstream river course is studied through the similarity analysis with the full ship and the determination of the maneuverability rate, and the main influencing factors are quantitatively analyzed in combination with the results of the experimental research. It provides a scientific and reliable data base for the design optimization of Xiangjiaba project.
