Seabed erosion and deposition prediction analysis system and method for submarine cable routing area

Abstract

The invention discloses a seabed erosion and deposition prediction analysis system and method for a submarine cable routing area. The method comprises the steps: constructing a seabed erosion and deposition prediction model of a to-be-predicted submarine cable routing area through an erosion and deposition prediction model construction module, wherein the seabed erosion and deposition prediction model comprises a hydrodynamic model, a sediment transportation model and a seabed deformation model; solving the seabed erosion and deposition prediction model through a solving module to obtain a seabed erosion and deposition depth prediction value of the to-be-predicted submarine cable routing area; correcting a seabed erosion and deposition depth prediction value through a correction module; predicting a future submarine cable burial depth value through a prediction module according to the corrected seabed erosion and deposition depth prediction value and a submarine cable design burial depth value or a submarine cable burial depth historical detection value; dividing the scour level of the to-be-predicted submarine cable routing area by an evaluation module according to the future submarine cable burial depth value, and then evaluating the scour risk level. The technical problem that an existing seabed erosion and deposition prediction analysis method is low in accuracy is solved.

Description

Technical field

[0001] The present application relates to the field of seafrice prediction analysis, and in particular, therefore, in particular, a seafris predictive analysis system and method for subsea cable routing areas. Background technique

[0002] Compared with the terrestrial cable, it has many superiority. Its layout does not need to dig a port or support, therefore, there is less investment, the construction speed is fast; and the seabed cable exists in a certain depth of seabed, less affected by human activities. . Therefore, the safety of seabed cable, high stability, strong anti-interference ability, good confidentiality.

[0003] In order to prevent local flushing from the sea cable, it is generally used to dig trenches in the sea, and the artificial manipulation is buried in the seafood to reduce the influence of waves or seafrons on the sea cable, but this method has undoubtedly increased the sea cable. The installation is difficult and budgetary; and the actual ...
