本論文主要目的在建立波浪作用下沉箱式防波堤與土壤之有限元素分析模式。文中海床土壤與拋石基礎部份視為多孔彈性介質,並以Biot’s 壓密方程式及彈性力學之力平衡方程式來控制。模式中利用波浪作用有週期性之特性,將時間變數自方程式及邊界條件中分離,並採用Galerkin’s法建立有限元素分析模式,沉箱部份則以二維八節點彈性元素來模擬。

In this study, a two-dimensional finite element model will be developed based on Biot's consolidation theory and force balances in poro-elastic theory, together with Galerkin's method. Based on the model, the wave-induced seabed response in the vicinity of a caisson breakwater (including soil effective stresses, pore pressure and seepage forces) will be calculated.
