目前，我国内河水运建设已进入快速发展阶段，未来10-20年将是我国大规模治理河流的重要时期，本文就内河水运如何抓住机遇，实施跨越式发展战略，提出了若干对策建议
结合洞庭湖区毛角口滩险滩整治工程设计,合理地将船舶物理模型、定床物理模型和平面二维水流数学模型等试验手段用于方案比选,对整治工程方案从改善通航条件、引起河道分流比变化、沿程水位变化、局部流态变化及整治工程对堤防安全的影响等方面作出了综合分析,为优选工程方案提供依据,并总结出了不同模型在此类工程应用上各自的特点.
Rational grading of waterway is the guarantee for sustainable development of water transportation.Based on the analysis of the current situation of China ' s inland waterway and problems in national standard GBJ139-90concerning waterway grading,this paper puts forward a suggestion on raising the standard of the lowest waterway grade and gives the definition of high-grade waterway.
The material characteristics, structural design, balance mechanism and force analysis of inland river new-type collision-resistant buoy are briefly introduced. This type of buoy has passed site test and expert appraisal and is a patent product with remarkable economic benefit.
