Problems solved by technology

At present, the observation technology of lateral deformation and sliding of shallow seabed sediments at home and abroad is relatively mature, but there is little research on the deformation and sliding observation technology of regional seabed surface sediments
The deformation and sliding observations of surface sediments are mostly qualitative analysis after occurrence, lacking quantitative observations of sliding distance and sliding direction
At present, there is no ideal observation method to directly obtain the evolution process of seabed surface sediment deformation and sliding, which seriously restricts the research on disaster mechanism and the development of monitoring and early warning technology.

Embodiment 1

[0055] Such as Figure 1-Figure 8 As shown in , a long-term observation device for deformation and sliding of seabed surface, including the indwelling part ( figure 2 ) and the recycling section ( image 3 ).

[0056] Such as figure 2 (can show the structure of the device of the present invention more clearly for accompanying drawing, appended figure 2 Only one auxiliary measurement unit is shown in , and the remaining three auxiliary measurement units are omitted), the indwelling part includes a central measurement unit and four auxiliary measurement units.

[0057] The bottom of the central measurement unit is a suction anchor 16, the upper part of the suction anchor 16 is fixedly connected to the support frame 14, and the middle part of the support frame 14 is fixed with a stop disc 15. A support panel 13 is fixedly arranged above the support frame 14 . The support panel 13 is rectangular, and each corner attachment of the support panel 13 is provided with a main meas...

Embodiment 2

[0112] The difference from Embodiment 1 is that three main measuring columns and three auxiliary measuring units are provided, and the opening of the measuring opening on each main measuring column is 120°.

Abstract

The invention discloses a long-term observation device and method for seabed surface deformation and sliding, and belongs to the technical field of seabed observation. The device of the present invention includes a central measurement unit and several auxiliary measurement units, through the cooperation of the central measurement unit and the auxiliary measurement units, the quantitative data of deformation, sliding displacement and sliding orientation of the seabed surface within a certain area can be measured; the sedimentation of the seabed surface can be realized In-situ long-term observation of the deformation and sliding displacement and orientation of sediments, and has a wide range of measurement characteristics, which can measure the deformation and sliding process of regional seabed surface sediments.

Description

technical field [0001] The invention relates to the technical field of seabed observation, in particular to a long-term observation device and method for seabed surface deformation and sliding. Background technique [0002] Deformation and sliding of the seabed surface is an intuitive phenomenon of a series of marine geological disasters such as submarine creep and submarine landslides, and can reflect the stable state of submarine slope sediments. However, the stability of submarine slope sediments is directly related to the safe development of submarine oil and gas resources. Cables and other important engineering facilities will bring huge dangers and losses. [0003] The reason for seabed surface deformation and sliding is, on the one hand, due to the internal structure and dynamic conditions of the sediment, such as the water content and clay content of the soft sediment on the seabed or the overpressure fluid produced by the decomposition of natural gas hydrate, etc.;...
