Maritime work vibrating table device

Abstract

The invention discloses a maritime work vibrating table device which comprises a vibrating table, an actuator, a model soil box and a wave pool. The actuator is connected with the vibrating table and is used for driving the vibrating table to vibrate and controlling the vibrating process of the vibrating table. The model soil box is arranged on the vibrating table, and a seabed soil layer is arranged inside the model soil box. The wave pool is used for generating waves and flow inside the wave pool, an opening is formed in the bottom wall of the wave pool, and the top end of the model soil box is connected with the bottom wall of the wave pool in a sealing mode on the opening so that the wave pool can be communicated with the model soil box through the opening. According to the maritime work vibrating table device, the process of ocean currents, sea waves and strong earthquakes can be represented simultaneously, the dynamic interaction among ocean fluid, undersea strong earthquakes, a maritime work structure and a seabed soil layer can be achieved, the multi-field coupling effect of a typical maritime work structure and a seabed soil layer under the effect of extreme waves, ocean currents and undersea strong earthquakes is achieved, and a large-scale experimental verification platform can be provided for ocean engineering geological prospecting design and a marine construction technology.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a marine vibration table device. Background technique [0002] As my country develops marine economy, develops marine resources, and guarantees maritime security, it is necessary to solve the technical problems contained in the safety of marine structures in complex marine environments. The existing marine equipment used for ships and port engineering cannot simultaneously reproduce the Bed soil, waves, ocean currents, and submarine seismic processes cannot be used to simulate the multi-field coupling between typical marine structures and seabed soil under extreme waves, ocean current loads, and submarine strong earthquakes. Therefore, there is a need for improvement in existing offshore equipment. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For th...
