Numerical Simulation Of Wave Buoyancy On Board Of High Pile Wharf By Using Unsteady Reynolds Equations Models

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.
