【摘要】 在全球经济高速发展的今天,沿海港口船舶大型化趋势愈发明显。随着船舶大型化和数量的不断增多,全球经济大幅增长,港口建设也遭遇了新的挑战。近年来,随着深水码头、深水航道探索的不断深入,我国已建设了大量的开敞式深水码头,标志着船舶大型化、港口深水化、泊位离岸化的趋势正逐步走向巅峰。长兴岛30万吨油码头工程位于大连市长兴岛西北部的北港区。本海区风、浪、流条件恶劣,且冰情严重,冰期长达90天,最大浮冰块水平尺度达2120m,厚度大于30cm。本文针对大连港长兴岛30万吨油码头工程实例,考虑泊稳因素的影响,并根据物理模型实验结果,分析船舶运动量、撞击能量以及系缆力的大小,对码头平面布置方案和兼顾船型(10万吨油船)布缆方案进行了优化。同时考虑浮冰的影响,在常规重力式圆沉箱结构上设抗冰锥体作为优化,并在重要结构应力、工程量、概算等方面进行了方案比较。本文对码头平面布置与码头主体结构的几种方案进行了深入的优化分析,为开敞式大型油品码头的设计提供了参考和借鉴。更多还原

【Abstract】 With the rapid growth of global economy, the trend of upsizing ships at costal ports is gradually obvious. The construction of ports faces new challenges when the size and the number of ships are increasing. Recently, following the exploration of deepwater wharfs and deepwater lanes, China has constructed large numbers of open type deepwater wharfs. This marks that the trend of ship upsizing, deepwater ports and offshore berths is stepping to peak.The300,000tons oil wharfs project of Changxing Island locates at north harbor district of northwestern island. The wind, wave and stream of this sea area are bad. What’s more, the condition of ice is serious. The ice period lasts about90days. The maximize horizontal scale of floe is2120meters. The thickness of floe are more than30centimeters. This paper focuses on Dalian Changxing Island’s300,000tons oil wharfs project and takes the effects of steadiness of porting into consideration. Then it introduces two programs on the wharf’s plane layout. Subsequently, according to the experiment results of physical model, it analyzes the bombardment energy and the strength of heaving pile and optimizes the length of the berth. Meanwhile, considering the effects of floe, it proposes two wharf major structure programs consisting of conventional gravity type caisson structure and round caisson with cones resisting to ice. This paper make a thorough comparative analysis of the existing projects of the wharf’s plane layout and major structure. It makes a reference to the design of the open type large oil wharf.更多还原
