Embodiment Construction

[0027] Such as figure 1 , figure 2 As shown, this embodiment is a test device for simulating submarine landslides, which has a model box 1, a slideway 13, a mudflow generating mechanism and a monitoring mechanism.

[0028] In this embodiment, the model box 1 is a cuboid box structure with an open top, and the side panels arranged along its length direction on the model box 1 are glass surfaces, through which the inside of the model box can be observed. The model box is provided with a slideway 13 arranged obliquely along the length direction of the model box. The lower end of the slideway 13 is rotatably connected to the support plate 7 via a rotating shaft. The support plate 7 is fixed on the model box 1. The upper end of the slideway 13 is connected by a slideway inclination adjustment mechanism. Model Box 1.

[0029] In this example, the slideway inclination adjustment mechanism has a motor 3, and the motor 3 is fixed on the model box 1, and a steel wire rope is wound on...

Abstract

The invention relates to a testing device for simulating a submarine landslide and a testing method thereof. The invention aims to provide the testing device for simulating the submarine landslide which is simple in structure and convenient in operation and the testing method thereof. Through the technical scheme, the testing device for simulating the submarine landslide is characterized in that the testing device is provided with a model casing; the model casing is provided with a glass face convenient to observe the internal situation of the model casing; the model casing is internally provided with a slantly arranged slide rail; the lower end of the slide rail is rotatably connected with a supporting plate; the supporting plate is fixed to the model casing; the upper end of the slide rail is connected to the model casing through a slide rail inclination adjusting mechanism; the upper surface of the slide rail is covered with a cushion layer; a mudflow generating mechanism for releasing mud is arranged above the upper part of the slide rail; and a monitoring mechanism for monitoring the state of the mud on the slide rail is arranged corresponding to the slide rail. The testing device is applicable for the field of ocean engineering research.

Description

technical field [0001] The invention relates to a test device and a test method for simulating submarine landslides. Applicable to the field of marine engineering research. Background technique [0002] Submarine landslides are one of the most important sedimentation processes that transport sediments from shelf breaks to abyssal basins. Submarine landslides can slide hundreds of kilometers away at high speed by virtue of the "water slide" effect when the slope of the terrain is small, and the debris flow formed by it can seriously endanger offshore oil and gas development platforms, oil and gas pipelines, submarine cables and other facilities. With the increasing development of deepwater oilfields at home and abroad, the instability of the seabed caused by this sedimentation has been paid more and more attention. Therefore, the research on the mechanism of submarine landslide and its geological risk should also be strengthened. [0003] At present, the landslide model te...
