【摘要】：非恒定流對(duì)下游河道通航條件影響是向家壩工程實(shí)施時(shí)需要考慮的主要問(wèn)題。傳統(tǒng)的通航條件影響研究,不能全面準(zhǔn)確反映航道水流條件和邊界條件對(duì)船舶航行的綜合影響以及船舶與航道水流條件的相互作用。利用小比尺船模測(cè)控技術(shù),通過(guò)與實(shí)船相似性分析和操縱性能率定,試驗(yàn)研究向家壩非恒定流對(duì)下游河道通航條件的影響,結(jié)合試驗(yàn)研究成果定量分析主要影響因素,為向家壩工程方案的設(shè)計(jì)優(yōu)化提供了科學(xué)可靠的數(shù)據(jù)基礎(chǔ)。
[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.
