This paper investigates the effects of structureparameters on dynamic responses of submerged floatingtunnel (SFT) under hydrodynamic loads. The structureparameters includes buoyancy-weight ratio (BWR), stiffnesscoefficients of the cable systems, tunnel net buoyancy andtunnel length. First, the importance of structural damp inrelation to the dynamic responses of SFT is demonstratedand the mechanism of structural damp effect is discussed.Thereafter, the fundamental structure parameters are investigatedthrough the analysis of SFT dynamic responses underhydrodynamic loads. The results indicate that the BWR ofSFT is a key structure parameter. When BWR is 1.2, there isa remarkable trend change in the vertical dynamic responseof SFT under hydrodynamic loads. The results also indicatethat the ratio of the tunnel net buoyancy to the cable stiffnesscoefficient is not a characteristic factor affecting the dynamicresponses of SFT under hydrodynamic loads.
