[0029] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure.

[0030] As described in the background technology, the existing landslide test devices in the related art cannot simulate the long-distance and high-speed movement of the sliding body, and it is difficult for the existing landslide test devices to accurately simulate the movement of the sliding body under variable environmental parameters, thereby limiting the effectiveness of simulating real landslide disasters. Specifically:

[0031] As a major natural geological disaster, landslide disasters cause huge economic losses and casualties every year due to their wide distribution and strong destructiveness. In recent years, affected by global warming, strong earthquakes, and frequent extreme meteorological events, especially affected by the rising temperature brought by global warming, the warming and humidification of the plateau has intensified, the ice and snow have melted, and the permafrost has seriously degraded. At the same time, because of the frequent occurrence of inducing factors such as rainfall, earthquakes, and rockfalls, a large number of high-speed long-distance landslide disasters have been induced. The causes of high-speed long-distance landslide disasters are complex, the start is sudden, and they are highly hidden and sudden. They threaten human life safety, damage infrastructure (houses, roads, bridges), and affect the implementation of major projects. At present, landslide disasters show a trend of increasing number, increasing scale, increasing impact range, and increasing losses. It has become one of the most widespread natural disasters encountered by people in life. Many places are deeply affected by landslide disasters, posing a huge threat to mountain buildings and personal and property safety. Therefore, it is necessary to study the movement characteristics and disaster-causing mechanisms of high-speed long-distance landslides in order to prevent and deal with this disaster that poses a huge threat to social and economic property and people's life safety. However, the current research on high-speed landslide disasters involving the influence of multiple physical fields such as water, heat, and force is very limited. Its complex external conditions and lengthy disaster chain process have brought many challenges to research in this direction.

[0032] Model test is an effective method to study landslide disasters. It can be combined with field investigation to obtain the rock and soil properties and terrain parameters of the landslide area to flexibly design and effectively control the test, and reproduce different disaster conditions. Actual landslide disasters are characterized by short occurrence time and large scale of destruction. It is impossible to artificially reproduce such naturally occurring landslide disasters, and it is impossible to control the inclination, speed or volume of such natural landslide disasters. Model tests can control and observe the inclination, speed, volume and other factors of the target working conditions under set conditions, or reproduce a specific landslide disaster in a targeted manner. Especially for landslide disasters with complex initial conditions, it can simulate landslide disasters and analyze the disaster-causing mechanism under different working and environmental conditions by changing the rock and soil parameters, slope and landslide terrain conditions in the source area. It is a highly feasible and reliable test method. At present, the existing conventional landslide tests still lack simulation devices that can comprehensively carry out multi-field coupling tests such as displacement field, temperature field, flow field, etc. At this stage, the research scope of landslide disasters has gradually transitioned from a single debris flow or sliding body structure to a complex fluid-debris flow transition structure with solid-liquid coupling or solid-liquid-gas three-phase coupling under multi-physical field conditions. However, there is currently a lack of test devices or test methods that can adjust the disaster-causing conditions or conduct refined observations on this form of fluid-like or debris flow structures.

[0033] In summary, the background technology of fixed landslide test devices reflects the need for a deeper understanding of the mechanism of landslide disasters. These test devices provide important experimental means for landslide research, helping scientists and engineers to better predict and prevent landslide disasters. Fixed landslide test devices mainly conduct single landslide tests on soil structures. Generally, the chute device consists of chutes at both ends, material boxes, excitation gates, and concave steel plates. The chute is divided into an inclined section, a concave section, and a horizontal section. The inclined section can adjust different slopes. Figure 1 This type of test configures a sliding soil structure to test a specific water-containing or water-poor sliding body sliding down a fixed slope. After the test starts, the excitation door is opened to allow the material to pour out of the trough and move down the slope. Digital cameras and high-speed cameras are used to record the information, and sensors on the chute are used to collect sliding movement information. Finally, image processing technology is used to analyze the sliding state.

[0034] However, in the related art, although fixed landslide test devices have made certain progress in simulating landslides, they usually have some limitations, such as limited slide length, inability to simulate long-distance movement, and unadjustable inclination angle and speed.

[0035] Fixed landslide test devices can usually only perform single, static landslide simulations and cannot simulate changes in speed and inclination during landslides. The movable landslide test device adds a movable part to the fixed landslide device, which can further simulate the impact of different landslide angles on the movement of the sliding body. In the actual landslide disaster process, the sliding body structure often does not move along an ideal sliding surface fixed at a certain angle. Figure 2 By setting the inclination adjuster, the movable landslide test device has a certain inclination angle to give the landslide body a downward force, so that the sliding body moves downward along the transmission belt.

[0036] However, the current mobile landslide test equipment can only carry out sliding body experimental simulation under the conditions of low speed and fixed inclination angle, and does not take into account the situation where the movement speed or inclination angle of the sliding body changes during the movement. The ability to simulate the actual movement state or environmental parameters of the sliding body is limited.

[0037] In order to solve the above problems, the present disclosure provides a remote landslide dynamic maintenance test device, which specifically includes:

[0038] A remote landslide dynamic maintenance test device, the device comprising: a box, an inclination adjustment device, a pair of traction rollers, a conveyor belt and an observation device, the inclination adjustment device is connected to the box and is configured to drive the box to tilt, the pair of traction rollers are arranged inside the box, the pair of traction rollers are arranged inside the box, and the conveyor belt is arranged between the pair of traction rollers; the pair of traction rollers can pull the conveyor belt to move, so that when the box tilts and the test material has a downward trend, the test material is kept stationary relative to the box, and the observation device is configured to record test information during the high-speed remote landslide dynamic maintenance test. The movable landslide test device disclosed in the present invention has an adjustable transmission belt rotation speed, and the direction of the transmission belt rotation speed is opposite to the direction of movement of the sliding body. The required rotation speed can be automatically matched according to the movement speed and movement inclination of the sliding body on the inclined plane, so that the sliding body structure and the landslide test device can achieve dynamic balance, and the sliding body structure can be maintained in a relatively stable position for stable and high-precision observation. The long-term and long-distance sliding body movement process is simulated by adjusting the transmission belt movement speed to match the movement state of the sliding body structure, and a high-speed remote landslide simulation test is realized with a smaller equipment size, thus overcoming the disadvantage that the conventional high-speed remote landslide model test site size requirement is large. In addition, the present invention solves the problem that the existing movable landslide test device cannot be used for multiple The problem of high-precision observation of the physical field is solved, and the problems of high movement rate, large change of movement inclination angle, low (high) temperature environmental conditions, and complex fluid-solid coupling process are further considered to carry out complex test conditions of single or multiple extreme conditions coupling; the movement speed and movement angle of the sliding body in the actual movement process change all the time as the sliding body structure passes through different terrains. The present invention solves the problem that the test rate and inclination angle of the current active landslide test device cannot be changed in real time after the test starts. The transmission belt speed and inclination are programmed according to the test-related and target terrain information, and the program information is written into the automatic control program. The space-time motion trajectory of the sliding body structure under the target terrain conditions is simulated through real-time regulation of the transmission belt slope and speed parameters.

The movement speed and movement angle of the sliding body in the actual movement process change all the time as the sliding body structure passes through different terrains. This device can also solve the problem that the test speed and inclination of the current active landslide test device cannot be changed in real time after the test starts.

[0096] In addition, although the operations of the disclosed method are described in a particular order in the accompanying drawings, this does not require or imply that the operations must be performed in this particular order, or that all the operations shown must be performed to achieve the desired results. On the contrary, the steps depicted in the flow chart can be performed in a different order. Additionally or alternatively, some steps can be omitted, multiple steps can be combined into one step, and / or one step can be decomposed into multiple steps.

[0097] The flowchart and block diagram in the accompanying drawings illustrate the possible architecture, functions and operations of the system, method and computer program product according to various embodiments of the present application. Wherein, each box in the flowchart or block diagram can represent a module, a program segment, or a part of the code, and the above-mentioned module, program segment, or a part of the code contains one or more executable instructions for realizing the specified logical function. It should also be noted that in some alternative implementations, the functions marked in the box can also occur in a different order from the order marked in the accompanying drawings. For example, two boxes represented in succession can actually be executed substantially in parallel, and they can sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram or flowchart, and the combination of boxes in the block diagram or flowchart can be implemented with a dedicated hardware-based system that performs a specified function or operation, or can be implemented with a combination of dedicated hardware and computer instructions.
