Description

technical field [0001] The invention relates to the technical field of marine geological disasters, in particular to a submarine landslide simulation system based on wave vibration, which is mainly used to study the dynamic response and trigger mechanism of submarine landslides under the action of wave loads. Background technique [0002] As a very destructive marine geological disaster, submarine landslides have a major destructive effect on offshore projects such as submarine optical cables, wind power pile foundations, port terminals and drilling platforms, and bring immeasurable damage to the development of coastal areas and the safety of people's lives and properties. loss. Because the occurrence environment of submarine landslides is obviously different from that of land landslides, the genetic mechanism and triggering factors of submarine landslides are relatively complex. Therefore, in recent years, the relevant research on submarine landslides has gradually become ...
