摘要： 在一定浅水条件下, 浅水波浪将以孤立波形态对近岸结构施加作用。文章基于孤立波对圆柱的绕射理论和渗流问题的Biot固结理论, 分析了由孤立波所引起的立柱以下弹性海床内波浪渗流压力分布问题, 推导了对圆柱绕射孤立波的波浪渗流压力场的数学解式, 并据此对压力引起的墩柱底部所受渗流作用进行了实算。结果表明, 海况条件和结构的几何条件等因素的变化对孤立波引起的渗流浮托力和倾覆力矩均有一定影响。在一定条件下, 圆柱底部所受波浪渗流力与绕射波浪的直接作用可以具有相同量级。

Abstract: In certain shallow water condition, shallow water wave may emerge in solitary wave form, exerting wave loads on offshore structures. Based on solitary wave diffraction theory and Biot seepage consolidation theory, the problem of solitary wave-induced seepage pressure inside porous elastic seabed is analyzed, the mathematical solution to seepage pressure is deduced, and seepage loads on the bottom of vertical cylinder resting on porous seabed are evaluated. The results show that variations of ocean condition and structure geometry condition may have some influence on solitary wave-induced seepage uplift force and moment, especially on seepage moment. In certain condition, solitary wave-induced seepage loads may have the same order of magnitude as the direct horizontal wave load

Key words: solitary wave, diffraction, radiation, wave force, seepage, wave-induced seepage uplift force and moment
