【摘要】：内河水运在浙江经济社会发展中一直承担着十分重要的作用。一方面,浙江省经济社会的发展阶段决定了内河水运仍将保持持续而旺盛的需求,特别是对航道高等级化和网络化的要求更是十分迫切；另一方面,浙江省资源的承载能力对内河航道建设与发展的制约将日益凸现。两方面因素决定了浙江内河航道建设与发展必须走资源节约集约、高效利用之路。本研究通过分析浙江省内河航道现状、特点、发展规划、建设的制约条件和国内外的航道尺度技术标准,按现有规范和标准对研究范围内的航道尺度进行理论分析计算,得到符合规范要求的基本航道尺度；以基本航道尺度为初始条件,通过数值模拟计算、物理模型试验和实船试验,分析不同航道尺度与航速、航行阻力、下沉量、漂角、船行波、近岸流速和船舶操控性等因素之间的关系,提出在满足航道航行安全、货运量发展需求的前提下,在综合考虑船舶航行效率、环境友好(节能减排、生态保护)、建设成本以及社会影响等因素下的资源节约型限制性航道相关关键技术,以达到破解资源(特别是土地资源)紧张、节能减排、环境友好、减少投资、顺利推进项目和促进科学进步的目的。并通过实际案例检验本研究成果的有效性和可行性。
[Abstract]:Inland water transportation plays an important role in Zhejiang's economic and social development. On the one hand, the stage of economic and social development in Zhejiang Province determines that inland waterway transportation will still maintain a sustained and vigorous demand, especially the demand for waterway upgrading and networking; on the other hand, The resource carrying capacity of Zhejiang Province will restrict the construction and development of inland waterway. Two factors determine that the construction and development of inland waterway in Zhejiang Province must take the road of intensive resource saving and efficient utilization. Based on the analysis of the current situation, characteristics, development planning, construction conditions and the technical standards of waterway scale in Zhejiang Province, the paper makes theoretical analysis and calculation of the waterway scale in the scope of the study according to the existing norms and standards. Taking the basic channel scale as the initial condition, through numerical simulation, physical model test and ship test, the different channel scales and speeds, navigational resistance, sinkage, drift angle are analyzed. The relationship between ship traveling wave, near-shore velocity and ship maneuverability, etc., under the premise of meeting the requirements of navigation safety and cargo volume development, the ship navigation efficiency is considered synthetically, and the environment is friendly (energy saving and emission reduction). The key technologies related to resource-saving restricted waterway under the factors of ecological protection, construction cost and social impact, in order to solve the shortage of resources (especially land resources), save energy and reduce emissions, environmental friendliness, and reduce investment, The purpose of advancing the project smoothly and promoting scientific progress. The effectiveness and feasibility of the research results are verified by practical cases.
