| 摘 要： | 报道了应用边界积分方法模拟完全非线性孤立波的传播与直墙反射，给出了波形演变过程。结果表明，本模型对计算孤立波的传播与直墙反射是有效的。三阶Boussinesq方程的孤立波解比低阶方程的孤立波解更接近完全非线性的数值解.当来波波高增大时，孤立波直墙反射的相位滞后变小。若考虑大波高孤立波的直墙反射或波——波相互作用，一阶理论预报的相位滞后往往低估实际情况。

| Abstract: | Modeling the propagation and end wall reflection of a fully nonlinear solitary wave with the boundary integral equation method is reported in the paper. The results show that the model is efficient for simulating high amplitude solitary waves in propagation and their run ups at a vertical wall. The solitary wave solution to the third order Boussinesq equations may give a better result than that to the lower order equations. The phase locking period of a solitary wave reflected by a vertical wall becomes smaller as the amplitude of incoming solitary wave increases. |
