波浪特性对矩形沉箱所受波浪荷载的影响研究

Study on Influence of Wave Characteristics on Hydrodynamic Loads Acting on Rectangular Caissons

为研究海洋环境中波浪特性对矩形沉箱水动力荷载的影响,基于有限差分软件Flow-3D建立了波浪-矩形沉箱相互作用的三维数值模型。首先对新建模型的计算精度进行了验证,然后基于此模型系统地研究了波高、波浪周期及水深对沉箱波浪荷载的影响。研究表明随着波高增大、波浪周期增长及水深的增大,矩形沉箱所受波浪荷载逐渐增加。本文研究成果可为同类海洋结构物的水动力荷载分析提供参考。

In order to study the influence of wave characteristics on hydrodynamic loads acting on rectangular caissons in ocean environment,a 3D numerical model for the interaction between wave and rectangular caisson is established on the basis of Flow-3D finite difference software.Firstly,the calculation accuracy of new model is verified,and then the model is used to systematically study the influence of wave height,wave period and water depth on wave loads acting on caissons.The results show that the increment of wave height,wave period and water depth leads to larger wave loads on rectangular caissons.The research results may provide a reference for the analysis of hydrodynamic loads on similar marine structures.
