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。     

厦门港嵩屿港区潮流特性物理模型试验

厦门港嵩屿规划港区位于两股潮汐水流分流、汇流处,水流流态复杂导致规划码头岸线前沿水域存在缓流区和回流区。涨、落潮流态对港区平面布置十分敏感。岸线方案如不能满足两股水流的分流要求,将在码头前沿水域产生大尺度回流区或导致泥沙严重回淤。进行24组物理模型试验,确定嵩屿港区布置方案。现场实测资料表明,物模试验成果能较好地预测嵩屿港区建成后的水流条件。     

宝钢马迹山矿石码头工程潮流问题研究

上海宝钢马迹山中转港扩建卸船码头东端涨潮水流湍急,水流流向与码头走向之间有20°左右的夹角,影响船舶靠离泊安全。模型试验表明,整治工程"东导流堤"可以有效地改善扩建卸船码头东端水流条件。西侧的装船码头水域范围内,由于马屁股岬角的挑流作用,落潮期在装船码头水域形成大尺度回流区;模型试验表明,采用整治工程"西导流堤"的"中"或"北"方案,均可解决装船码头水域回流问题;不宜采用布置在马屁股岬角处的"南方案"。     

杭州湾及洋山深水港动力和泥沙条件分析

杭州湾为强潮河口湾,在杭州湾喇叭口地形条件下,向湾内潮流逐渐增强。杭州湾水体泥沙主要来源于长江口,由于众多岛屿的掩护作用,湾内泥沙输移主要受控于潮流。洋山深水港水域动力和泥沙条件基本也遵循上述规律。杭州湾海域总体上呈冲淤基本平衡、略有淤积形势。据此分析了洋山深水港水域动力和泥沙输移特点,总结出深水港方案规划的16字方针:"封堵汊道、归顺水流、减少回淤、航行安全"。

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.
