  • The submerged floating tunnel (SFT) was simplified as an elastically supported beam with uniform supporting spacings. The dynamics model was established to solve the vibration problem of the SFT under impact loads. With the Galerkin method, the timedisplacement responses at the central cross section of the SFT was numerically simulated. The influences of the anchor stiffness, the impact mass and the impact velocity on the SFT’s central displacement were analyzed. The present results indicate that the anchor stiffness has significant but bounded negative influence on the SFT’s central displacement. Moreover, the impact mass and the impact velocity have obvious positive effects on the SFT’s central displacement. The work provides a theoretical reference for further study and construction of the SFT.
