【摘要】 随着开发海岸带资源的需要,人们在海岸和近海地区愈来愈多地兴建各种透空式建筑物,如顺岸式码头、岛式码头、人工岛、栈桥、港外系船柱以及海上平台等。这些建筑物的大型实体部分一般由置于静水面以上的水平面板构成,常常处于无掩护的条件下,其下部将直接遭受波浪的袭击,而发生严重破坏。国内外曾多次发生因面板高程设计不当,而造成海上建筑物上部结构破坏。因此波浪与结构物的相互作用是海岸、海洋工程设计、施工和管理中十分重要的问题。早期研究波浪和海工结构物相互作用主要是实验室中的模型试验,并积累了许多经验公式。随着计算机和计算技术的发展,用数学模型来模拟波浪和结构物相互作用取得了很大进展。本文基于交通部“高桩码头面板波浪上托力计算”重点基金项目,通过建立波浪与结构物相互作用的二维数学模型,对高桩码头面板在一系列波况下所受波浪上托力进行了数值模拟计算,分析了波陡、超高、板宽等因素对面板所受上托力的影响。更多还原

【Abstract】 Because of the demand for exploring the costal area resources, more and more constructions are built in the offshore and costal areas, such as alongshore dock, island-like dock, man-made island, trestle, bollard out of the port and offshore platform. The entity part of these constructions is mainly constructed of plan boards above the still water surface, which are always without any protection, and the lower part of the plane boards are directly struck by the water wave, which sometimes lead to serious destruction. The unsuitable design of the board’s water level results in the destruction of offshore construction’s above-water part, which have happened many times in our country and foreign countries. So, the interaction between water wave and marine constructions is a very important problem in the costal engineering management and design.The early research of the interaction between water wave and marine constructions is mainly carried out by model experiment in laboratory, and it gives out a lot of empirical equations. As the development of computer and computing technologies, using numerical model to simulate the interaction between water wave and marine constructions has achieved great advancement.This study is based on the major fund project from the ministry of communications. By establishing a two-dimensional model to simulate the interaction between water wave and marine constructions, the buoyancy on the high pile wharf board is simulated and calculated in series of wave cases, meanwhile, the wave steepness, distance between water surface and the bottom of the board, the width of the board’s influence to the buoyancy on the board is analyzed in these cases.更多还原
