Abstract：
A theoretical study of the frequency domain dynamic response of an anchor cable of a submerged floating tunnel under random wave force excitation is presented and a mathematical method is established by the pseudo-excitation and Galerkin methods, and the non-linear motion equation is solved by the equivalent linearization method.The effects of parameters for wave and structure under non-stationary and stationary random excitation on the dynamic response parameters for the vibration system are analyzed. Compared with the results obtained from the Sunshengnan method and the hydrodynamic software AQWA, it shows that the proposed method can truly reflect the actual oceanographic conditions for meeting the requirement of accuracy.
