针对三峡船闸运行以来,过闸货运量快速增长,过闸船舶大型化趋势明显的问题,建立三峡船闸通过量与过闸船舶吃水控制标准关系数学模型,并以2010年过闸船舶数据为基础,测算不同吃水控制标准条件下的船闸通过量,提出利用三峡河段丰富的水资源优势,合理挖掘船舶吃水深度潜力,充分发挥过闸船舶的装载能力,进而有效提高三峡船闸通过量的建议。 相似文献

针对三峡船闸过闸需求增加和船舶大型化发展对允许过闸船舶的最大吃水需求的问题,在相关管理规范基础上结合模型研究,分析三峡船闸门槛水深、船舶航行下沉量及安全富余水深要求,以三峡船闸门槛水深5.125 m、5.5 m和6 m为参考,分别确定该水深期间允许过闸船舶的最大吃水,为对外发布吃水控制标准提供依据,对过闸船舶配载发挥指导和参考作用。 相似文献

将三峡过闸船舶的吃水和载货量视作一组离散的数据,对船舶最大吃水、定额吨和实载吨等3个变量之间的关系进行拟合分析,提出运用插值方法确定实际过闸船舶的最优吃水。对连续观测的三峡船闸2014年的22 065艘次下行过闸船舶的数据进行预处理,构建船闸门槛水深与允许过闸船舶最大吃水的计算模型。运用数理统计对8个区间的变量值进行聚类分布。运用MATLAB中分段线性、边界条件为Latrange和二阶导数的三次样条插值运算方法对样本数据进行拟合。结果表明:以二阶导数为边界条件的三次样条插值可解决该问题,当允许过闸船舶的吃水控制在3.92~4.38 m时,过闸船舶装载率为最佳。 相似文献

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region. 相似文献

无人反潜系统的指挥控制问题是关系其具备实际作战能力的主要问题之一。论文在分析无人反潜系统指控原理和其自主指控水平分级的基础上,采用可变自主控制结构,研究了无人反潜系统分级可变自主指控实现的方法。该方法可赋予无人反潜系统可变的指挥控制自主性,使其在工作环境中能够实时评估自身的自主能力,并主动引入人工干预。这种具备人机智能融合特性的自主指挥控制方法更适应无人反潜系统在复杂战场环境中实战化的需求。 相似文献

在船长与引航员的法律关系上,存在一些比较流行的观点和看法,却未必经得起法律思考,缺乏一定的法律依据。将《劳动法》、《合同法》、《海商法》、《船舶引航管理规定》等法律、法规和部门的规章作为依据,从法律的角度分析船长在实际工作中遇到的问题,使船长从法律的高度正确认识船长与引航员的关系,有利于船长与引航员之间关系的认识和处理,达到驾驶台团队的和谐、驾驶台资源的充分利用,进而达到增强和改善港内引航安全,做好船舶安全管理工作的目的,同时也为了避免或减少在实践中造成行政违法行为的发生。 相似文献
