Abstract

Abstract

The submerged floating tunnel stayed by tension legs was simplified as the superposition of an elastic beam and an elastically supported rigid beam, the motion equations of forced vibration for the floating tunnel tube based on the BernoulliEuler beam theory were presented, then the nonlinear term of the dynamic equations was linearized equivalently. The pseudo excitation was input to simulate the random seismic impact and study the response of the submerged floating tunnel tube, with the displacement power spectrum at the middle point given and discussed detailedly. The displacement power spectrum analysis indicates that the displacement response of the tube decreases with the spring stiffness of the supporting tension legs and the damping coefficient of the energy dissipation devices, of which the former is of much higher significance.
