چکیده انگلیسی
In this paper, taking the Jiaozhou Bay Subsea Tunnel with a curved wall in Qingdao as the research background, while assuming that the liquid cannot be compressed and considering the effect of surface gravity waves, a harmonic wave is used to simulate a sea wave. Considering coupling effect of stress and seepage fields, dynamic responses of subsea tunnels under the action of ocean waves and earthquakes are discussed. The results show that with an increase in water depth, the maximum equivalent stress, the first principal stress, the third principal stress and the displacement of the tunnel structure all increase. When the water depth reaches a certain value, the influence of sea waves on the calculation results is so small that it can be ignored, and the influence of the sea wave on the displacement is smaller than that on the stress. After considering sea waves, the increases of velocity and acceleration with different sea water depths are far less than 5% under the action of an earthquake. The influence of sea waves on dynamic responses of subsea tunnels may not be considered when the sea water depth is more than 40 m.
