长江上游大水位差直立式集装箱码头装卸工艺 总被引:1,自引:0,他引:1
1 问题的提出 长江上游河段属山区河流,岸坡陡,水位差大,年最大水位变幅可达30~40 m.根据<河港工程设计规范>(GB50192-93)中的装卸工艺一般规定,设计水位差17 m以上宜采用斜坡式码头.以往长江上游地区集装箱泊位一般都据此建设斜坡式码头,例如重庆九龙坡集装箱专用码头.该斜坡式码头前沿系靠船设施为浮式趸船,趸船上配置2台固定回转起重机,斜坡道上配置4台横向缆车,坡顶采用轨道式集装箱门式起重机. 相似文献

根据模型试验结果,分析三峡建库后泥沙淤积对川维码头的影响,结果表明:建库后,本河段自然条件下河床淤积、冲刷规律有所改变,导致码头前沿及斜坡式码头泥沙大量淤积,影响码头作业条件。 相似文献

根据规范方法并结合工程实际和内河大水位差码头关键技术问题,依托大量的数值计算,对内河大水位差架空直立式码头在各种荷载组合下的灾害进行了预测。利用ArcView将预测结果与地理信息系统有效地结合起来,建立了内河大水位差架空直立式码头灾害预测与管理系统,实现了港口安全评估的动态化管理。通过对系统测试数据的评估,可以有效提高码头的装卸效率,实时评估码头的安全性能。 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

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues. 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
