Many coastal structures have been constructed to attenuate wave condition, to provide production, transportation or recreational facilities and to prevent beach erosion and attract sediment. However, some of them were damaged and some triggered environmental deterioration. These unexpected results are caused mainly by the lack of appropriate evaluation of seabed response to nearshore waves and currents. The interactions between wave and seabed, and between a structure and seabed, which are thus important to design of coastal structures yet little known, are complicated by transforming random wave field, by difficult pore pressure measurement, and by necessity of integrating a broad range of knowledge from fluid mechanics to soil mechanics. We propose to develop the methodology to design coastal structures in the nearshore zone which includes: (1) transformation model for random waves, (2) numerical model to estimate wave motion after breaking, (3) taking account of the seabed response is required to perform the stabilizing coastal structures.

许多海岸建筑物的建造是为了减弱波浪条件，提供生产、运输或娱乐设施，防止海滩侵蚀和吸引沉积物。然而，其中一些遭到破坏，一些引发了环境恶化。这些意想不到的结果主要是由于缺乏对海底对近岸波浪和洋流的反应的适当评估。波浪与海床之间、结构与海床之间的相互作用对海岸结构的设计具有重要意义，但鲜为人知，但由于随机波场的转换、孔隙压力的测量困难以及从流体力学到土力学的广泛知识的需要，这些相互作用变得复杂。我们建议发展近岸区海岸结构的设计方法，包括：(1)随机波的变换模型；(2)破碎后波浪运动的数值模型；(3)考虑稳定海岸结构所需的海底响应。
