Hydrodynamic pressures analysis of submerged floating tunnel under coaction of seismic SV wave and ocean wave
https://orcid.org/0000-0002-9378-0303
Submerged floating tunnel (SFT) is an innovative traffic structure for crossing long waterway or deep straits. To investigate the hydrodynamic pressure acting on the SFT under coaction of seismic SV wave and ocean wave, a theoretical model is developed for considering the effect of marine sediment. According to the displacement potential functions and linear wave theory, the reflection and refraction coefficients of wave action in different media are derived. Numerical examples are illustrated to analyze the hydrodynamic pressure distribution. The results show that the hydrodynamic pressure has a spatial difference along the SFT longitudinal direction when the structure operating in the water subjects different incident phase ocean wave. Wave incidence frequency not only changes the loading action mode but also affects the amplitude of the hydrodynamic pressure. Besides, due to the ocean wave loading combined, the effect of saturation on the hydrodynamic pressure load on the structure is not obvious. And the dense arrangement of tethers is recommended to the structure construction.
