| 摘 要： | 采用求解Beji和Nadaoka改进的Boussinesq方程,模拟了波浪在多个串连大圆筒结构前的反射,得到了作用于圆筒结构上的波浪力。空间离散采用有限元方法,可以较好地适应圆筒结构表面形成的复杂边界形状。数值模拟结果与公开发表的物理模型试验成果进行了比较,符合较好。

| Abstract: | By solving the Boussinesq equations improved by Beji and Nadaoka,this paper simulated the reflection of wave in front of the wharf constructed by aligned large cylindrical caissons and obtained wave force on the caissons.Finite element method was used in the variance to get a good agreement with the complex boundary condition of cylindrical structures.The numerical simulation results tally well with the findings of physical model test. |
