Embodiment Construction

[0040] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The following descriptions in the specification are preferred implementation modes for implementing the present invention, but the descriptions are for the purpose of illustrating the general principles of the present invention, and ...

Abstract

The invention discloses a simulation and observation system for submarine landslide caused by natural gas hydrate decomposition. The simulation and observation system comprises a mechanical support, a heating decomposition unit and a deformation measurement unit, wherein the mechanical support is used for providing a platform and support for the heating decomposition unit and providing an observation area for the deformation measurement unit; the heating decomposition unit is used for heating an observed hydrate material so as to be decomposed and feeding back the amount of decomposition information to the deformation measurement unit; the deformation measurement unit is used for collecting a deformation signal in the mechanical support, observing the deformation process after the heating decomposition unit heats an observed test piece for decomposition according to the deformation signal, and obtaining the digital speckle images of the profile of the test piece in chronological order to generate the deformation information of the test piece for storage. The simulation and observation system solves the problems that in physical simulation experiments in a laboratory, the amount of decomposition and the decomposition area of material samples similar with a hydrate cannot be precisely controlled, the slope angle of the sample cannot be controlled, the landslide deformation cannot be quantitatively described and the like.

Description

technical field [0001] The invention relates to the field of submarine landslide simulation and observation, in particular to a submarine landslide simulation and observation system caused by natural gas hydrate decomposition. Background technique [0002] Natural gas hydrate is generally considered to be the most potential new clean energy in the 21st century. my country's vast jurisdictional sea area, exclusive economic zone and permafrost areas have huge prospects for hydrate resources. The dissociation of seabed gas hydrate is a key factor in inducing some submarine landslides, and its mechanism is that the strength of seabed rocks is reduced due to the dissociation of hydrates. Therefore, when seismic waves, storm waves or man-made disturbances occur, submarine landslides or debris flows will be caused in the seabed hydrate stability zone. [0003] From the perspective of research methods, the current domestic and foreign research on the evaluation of the effects and s...
