一种内河复合式港池研究

在经济较发达地区的内河港区选址及总平布置设计中,经常会遇到主航道通航繁忙、港区纵深小、征地困难等不利于港区总平面布置的建港条件,尤其为不影响主航道通航安全而布置挖入式港池,对港区陆域布置影响较大。挖入式港池需要陆域有一定的纵深,需要较大的征地范围,这将增加工程投资;较小纵深会制约港区发展。为此,综合分析国内现有内河泊位布置形式,提出一种新型内河复合式港池布置。该种港池的船舶掉头回旋水域不占用主航道,港池水域面积小,泊位布置紧凑。在陆域纵深小、泊位数量多、主航道繁忙的港区,复合式港池布置独具优势。     

受限水域半潜驳码头平面设计

针对深中通道桂山岛预制场钢壳卸驳码头水、陆域受限的情况，对受限条件下半潜驳码头平面设计进行研究。采用船舶停泊水域和回旋水域分离布置方案，并布设岸上系缆柱辅助半潜驳多次转向和平移，解决半潜驳大角度转向靠泊问题。半潜驳进港移动轨迹证明该方案满足半潜驳靠泊码头的需要；卸驳码头水域布置突破了常规港池设计，减小码头水域的占用范围。

平直海岸填筑式港口布置水流条件研究

以绥中新港码头方案论证为例,针对平直海岸的水流特点,通过平面二维潮流数学模型对填筑式的突堤码头实施后的水流进行模拟计算,从港池、航道平面流态、码头和航道横流及工程建设对周边水域的影响等角度对码头工程实施的水流条件进行分析。分析认为,平直海岸码头前沿不宜突出岸线太多,相邻港池口门宜尽量布置在同一水平线上以避免口门附近出现复杂流态和减少相互影响;应尽量采用栈桥码头布置较大吨位泊位,可以减小围填工程对周边水流的影响。

考虑相邻工程的某港区总体建设方案

以某港区实际工程为例,在对建设条件梳理分析的基础上进行方案研究。针对复杂的掩护条件,根据周边工程实施进度分阶段确定掩护标准,选择合理的设计波要素。总体建设方案选择投资稍高但建设工期较短的离岸式高桩结构,先施工码头结构后再进行港池疏浚,有效缩短了建设工期。采用Plaxis岩土有限元软件分析港池疏浚对桩基的作用,结果表明考虑港池疏浚产生的土体变形后,桩基弯矩显著增大。本工程提出的分阶段确定掩护标准、码头离岸式布置、吹填形成陆域、先施工码头结构后疏浚港池的总体建设方案,取得了良好的效益。

Catalyzing Coastal Management in Kenya and Zanzibar: Building Capacity and Commitment

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.
