摘要
针对海洋工程中常见的小尺度桩柱结构,利用MATLAB软件编写程序,分别计算了基于Airy线性波浪理论和Stokes五阶波理论的考虑结构物与波浪相对运动和不考虑结构物与波浪相对运动情况下结构响应,对比分析了考虑相对运动和不考虑相对运动情况下结构响应的差别,并利用有限元软件ANSYS进行建模求解验证了本文结果的正确性.分析结果表明,两种情况下结构的响应存在较大差异,在实际工程计算中,有必要考虑结构物与波浪的相对运动.
Based on airy linear wave theory and Stokes 5th wave theory,a MATLAB program is written to calculate the structure response of small dimension pile under the wave loads considering and not considering the relative motion between the pile and wave.By comparing the results of the two cases,the difference of the response is found.The correctness of the program and the results is testified by using the FEM software ANSYS.And the results show that the structure response of the two cases is quite different,so it＇s necessary to take the relative motion into consideration in engineering practice.
