【摘要】 跨海桥梁工程的设计与建设提出了许多新的水动力学问题。本文以上海崇明越江通道工程、洋山深水港东海大桥工程为例,指出了跨海工程设计、施工、使用中有待研究的水动力学问题,概述了桥墩群对河口与海岸潮流场及床面调整的影响、桥墩桩基承台波浪水流力、桥墩局部复杂流动与冲剧等研究进展。本文认为,鉴于我国大型跨海工程建设无经验可循,组织队伍开展与跨海桥梁建设有关的水动力学关键技术研究,无疑将为工程设计与施工提供强有力的技术支撑,也是流体力学工作者义不容辞的责任。更多还原

【Abstract】 There are many new hydrodynamic problems proposed in the course of design and construction of bridges over estuarine and coastal waters. Taking the Chongmin Passage project in the Yangtze estuary and the Donghai bridge project of the Yangshan deep-water harbor as examples, some advances in hydrodynamic topics associated with the development of bridges in marine environments, including the impacts of bridge piers on tidal flows and adjustment of bottom, hydrodynamic loads induced by wave-current combination on piles and slabs, complicated flows around a bottom mounted pier and local scouring in estuarine and coastal environments are presented. It is reported that there are some challenging topics of bridge construction in marine environments to be solved by the scientists of fluid mechanics.更多还原
