Underwater Shaking Table Simulation Device and Method for Seismic Damage Effect of Submarine Pipelines

Abstract

The invention relates to the technical field of submarine pipeline performance testing, and discloses an underwater shaking table simulation device and method for the seismic damage effect of submarine pipelines. The device includes: a water tank, one end of which is provided with a wave maker and the other end with a wave-absorbing net; a shaking table, the bottom of the water tank is recessed downward to form an installation groove, and the shaking table is arranged in the installation groove and between the wave maker and the wave-absorbing net; a soil model box, arranged on the shaking table, the top of the soil model box is provided with an opening, and the interior is filled with test soil to form a seabed foundation which is flush with the bottom of the water tank; a pipeline model, arranged on the seabed foundation.
