Deep sea seabed instability disaster three-dimensional monitoring system

Abstract

The invention relates to a three-dimensional monitoring system for deep sea seabed instability disasters. The three-dimensional monitoring system comprises a front-end sensing unit, a middle-end information transmission unit and a rear-end integrated display control unit, wherein the front-end sensing unit obtains the parameter information sensitive to the seabed instability disaster environment of the target area and transmits the parameter information to the middle-end information transmission unit; the parameter information comprises the first parameter information and the second parameter information; the first parameter information comprises seabed water depth, seabed topography gradient, seabed mechanical characteristics, seabed acoustic characteristics, a heat flow value, seabed seismic activity and a stratum structure; the second parameter information comprises pore pressure and seabed deformation of seabed shallow sediments; the middle-end information transmission unit transmits the received parameter information to the rear-end integrated display control unit; and the rear-end integrated display control unit is used for storing and integrally displaying the received parameter information. According to the system, three-dimensional perception and integrated display control of submarine instability disaster environment sensitive parameters of different spatial dimensions and time scales are realized.

Description

technical field [0001] The invention relates to the field of submarine disaster research, in particular to a three-dimensional monitoring system for deep-sea submarine instability disasters. Background technique [0002] At present, in the deep seabed, especially in deep-water continental shelf slopes, deep-water island reef slopes and other sea areas, it is found that geological processes such as deep-sea bottom slope creep, sediment differential accumulation, and deep overpressure fluid release are likely to induce seabed instability and geological disasters. Due to the lack of long-term monitoring data on the disaster-forming environment and pre-disaster environmental factors of submarine instability, quantitative research on the disaster-causing mechanism and process of deep-sea submarine slope instability disasters is insufficient. More urgently, under the background of the rapid development of marine economy, the demand for construction and application of deep-sea subm...

Problems solved by technology

Due to the lack of long-term monitoring data on the disaster-forming environment and the pre-disaster environmental factors of seabed instability, quantitative research on the disaster-causing mechanism and process of deep-sea submarine slope instability disasters is insufficient.

More urgently, under the background of the rapid development of the marine economy, the demand for construction and application of deep-sea submarine engineering is increasing day by day, and deep-sea submarine instability disasters pose a greater threat to the safety of submarine engineering.

[0003] The environment of the deep seabed is complex, and there are multiple sources of disaster-causing factors for seabed instability, and there are large temporal and spatial differences

In the space dimension, the seabed sedimentation dynamic process, seabed sedimentation dynamic process, seabed interface deformation, shallow sediment strata structure, mechanical properties, and deep overpressure fluid release all have a greater impact on seafloor instability; from the time dimension It can be seen that factors such as seabed gravity creep and slope steepening occur very slowly, but after a long period of accumulation, large geological disasters can occur; greater damage
