在已给定某海区的深水设计波要素之后,推算浅海波高时,由于受到岬角阻挡及湾内水深地形的变化,而引起波浪的绕射和折射,加之波浪在浅水区传播,因底摩擦而使波能损耗,这都将促使波高衰减。并对波浪变形产生一定的影响。本文结合台山电厂煤码头工程项目,在计算浅水波要素时,综合考虑了上述这些影响因素,因此,使计算所得结果更能趋于合理,因而可供工程可行性研究阶段时参考。
Given the elements of the deepwater design wave in a certain sea area, the diffraction and refraction of the waves caused by the change of the headland block and the inland water depth due to changes in the water depth of the bay, together with the waves propagating in shallow water areas, are caused by the bottom friction Waves can be depleted, which will all contribute to wave attenuation. And have a certain impact on the wave deformation. Combining with the project of coal terminal in Taishan Power Plant, the above factors are taken into account in the calculation of shallow water elements. Therefore, the calculated results tend to be more reasonable and can be referenced for the project feasibility study stage.
