Description

Technical Field

[0001] The present invention belongs to the technical field of fluid simulation, and in particular relates to an indoor test device and a test method for simulating geological bulk disasters, which have simple structure, free variable adjustment and diverse detection signals. Background Art

[0002] In geology, geological bulk refers to a collection of materials that are formed under natural conditions or in the process of geological action, with no or very weak bonding between particles. Since there is often a lack of effective bonding between particles of such materials, they are prone to move or deform under the action of external forces, thus forming geological bulk disasters such as mudslides and debris flows.

[0003] Geological bulk disasters are sudden and unpredictable, and due to their fast flow rate, large flow and strong destructive power, they often destroy crops, transportation facilities and even villages and towns, thus posing a serious threat to people's lives and property safety. In order to reduce or even eliminate the hazards of geological bulk disasters, predecessors have conducted extensive research on the occurrence mechanism of debris flows and have achieved many results. However, the water and sand gathering process of geological bulk disasters is very complex and is the product of the combined action of various natural and human factors. Therefore, different regions, precipitation, topography, and geological structures will lead to large differences between the actual effects of geological bulk disasters and the results of theoretical analysis, so it is necessary to continuously revise the theoretical model of geological bulk disasters.

[0004] Debris flow simulation test is a common method for revising theoretical geological bulk disaster models. In the prior art, during the debris flow simulation test, the debris flow occurrence process and movement trajectory under different conditions are simulated, and the changes and sizes of the speed, impact force and seismic signal of the debris flow moving to the lower place are recorded to reveal the influence of precipitation, topography, geological structure and other factors on the formation of debris flow, and the possible degree of damage of the debris flow is evaluated accordingly, so as to propose targeted prevention and control measures and finally revise the theoretical model. However, the current debris flow simulation test device is mainly a single variable (such as volume, slope, height) test conducted indoors, and it is difficult to freely adjust the slope, volume and height of the test as needed; and most of the existing debris flow simulation test devices only focus on the acquisition of single or local debris flow simulation data, and it is difficult to simultaneously obtain the debris flow speed, impact force and vibration signal, as well as the shape after the debris flow ends, thereby limiting the simulation application scope of the debris flow simulation test device.

Data analysis: The acquisition controller 8 stores the above data, real-time motion characteristics, the farthest movement distance of the sample and the maximum lateral accumulation width, and then uses the analysis model to analyze the stored data to obtain the test results of simulating geological bulk disasters.

[0037] The A step comprises the following sub-steps: A10. Place the geological bulk samples in a natural environment in a well-ventilated and well-lit room and air-dry them to the predetermined moisture content; A20, sieving the air-dried bulk geological sample to obtain bulk geological samples with different particle sizes; A30, dyeing geological bulk particles of different particle sizes respectively to obtain a variety of geological bulk samples of different colors; A40.

The specific steps are as follows: A. Sample preparation: according to the test requirements, dry geological bulk samples of different particle sizes are mixed and loaded into a storage box (31); B. Preparation of the test device: According to the test requirements, the acquisition controller (8) controls the driving mechanism to adjust the tilt angle of the rectangular plate (21), and controls the telescopic rod (33) to adjust the height difference between the opening and closing door (32) on the lower end surface of the storage box (31) and the impact force test table (41); C. Process simulation: firstly, the impact force test system (4), the velocimeter (5), the vibration signal acquisition system (6), the image acquisition device (7) and the acquisition controller (8) are started, and then the opening and closing door (32) on the lower end surface of the material storage box (31) is controlled to open, so that the sample in the material storage box (31) slides to the upper surface of the impact force test table (41) at the bottom of the slope with an initial velocity of zero; D. Data and image acquisition: During the sliding process, the impact force test system (4), the velocimeter (5) and the vibration signal acquisition system (6) respectively collect corresponding data, and the image acquisition device (7) collects real-time motion characteristics; after the sliding is completed, the farthest movement distance and the maximum lateral stacking width of the sample are immediately measured; E. Data analysis: The acquisition controller (8) stores the above data, real-time motion characteristics, the farthest motion distance of the sample and the maximum lateral accumulation width, and then uses the analysis model to analyze the stored data to obtain the test results of simulating geological bulk disasters.
