Description

Technical Field

[0001] The invention relates to the field of environmental simulation design, in particular to a landslide simulation experimental device. Background Art

[0002] The occurrence of landslides is often closely related to a variety of factors, among which water level changes and precipitation are the two most sensitive factors that induce landslides. The periodic rise and fall of water levels will lead to the redistribution of internal stress in the shore rock and soil, while heavy precipitation will increase the water content of the rock and soil and reduce its shear strength, which will increase the risk of landslides.

[0003] In order to deeply study and understand how these factors affect the occurrence and development of landslides, scientists and engineers have been committed to developing experimental devices that can simulate these complex conditions. Traditional landslide simulation experiments often focus on the role of a single factor and are difficult to fully reflect the complexity of multi-factor coupling in the actual landslide process. Therefore, it is particularly important to develop a landslide simulation experimental device that can simultaneously consider the impact of water level changes and precipitation and integrate multiple monitoring methods.

[0004] The existing technical solutions are mainly concentrated in the field of landslide simulation experimental devices, most of which have the following characteristics:

[0005] Single factor simulation: Many existing landslide simulation experimental devices mainly focus on simulating the impact of a single factor such as water level change or precipitation on landslides. These devices observe the response of the landslide body by controlling the rise and fall of water levels or simulating precipitation processes, but often ignore the interaction between multiple factors.

[0006] Basic monitoring functions: Some existing devices will set up some basic monitoring equipment during the simulation process, such as displacement meters, stress sensors, etc., to record the deformation and stress changes of the landslide body under specific conditions. However, these monitoring methods are often relatively simple and it is difficult to fully reflect the complexity of the landslide process.

[0007] Lack of comprehensiveness and flexibility: Most existing devices are relatively fixed in design and function, and are difficult to flexibly adjust according to specific research needs. For example, they may not be able to simulate landslide processes under different slopes and precipitation intensities at the same time, nor can they control experimental conditions in real time to obtain more detailed data. Summary of the invention

[0008] The purpose of the present invention is to overcome the defects of the prior art and provide a landslide simulation experimental device to solve the problem that the existing landslide simulation experiment cannot simultaneously simulate the landslide process under different slopes and precipitation intensities, and cannot control the experimental conditions in real time to obtain more detailed data.

[0009] The technical scheme for achieving the above-mentioned purpose is: a landslide simulation experimental device, comprising: an experimental box, the two side plates of the experimental box are transparent plates; a landslide model, the landslide model is placed on one side of the experimental box, the landslide model is arranged into a slope structure, and different soil layer structures can be arranged inside the landslide model to simulate the geological conditions of a real landslide; a water level control and spraying system, the water level control and spraying system comprises a plurality of spraying heads arranged on the top of the experimental box, and the spraying heads can simulate precipitation on the landslide model in the experimental box; a monitoring system, the monitoring system is arranged opposite to the landslide model, and the monitoring system records the whole process of the occurrence and development of the landslide on the landslide model.

[0010] In a landslide simulation experimental device of the present invention, the slope of the landslide model is accurately adjusted by a telescopic device, and combined with a water level control and a spraying system, the process of precipitation affecting the landslide can be simulated more realistically, and precise control and real-time monitoring of the landslide simulation are achieved. In conjunction with the monitoring system records, intuitive and detailed data support is provided for researchers, which significantly improves the efficiency and accuracy of landslide mechanism research.

[0011] A further improvement of the landslide simulation experimental device of the present invention is that it also includes: a bottom plate, which is arranged at the bottom of the landslide model, and one end of the bottom plate close to the bottom of the landslide model is movably connected to the inner wall of the experimental box; a telescopic device, which is supported at the bottom of the end of the bottom plate away from the bottom of the landslide model, and the telescopic device can be extended and retracted up and down to control the inclination angle of the bottom plate and drive the slope change of the landslide model.

[0012] A further improvement of the landslide simulation experimental device of the present invention is that the water body of the simulated precipitation of the water level control and spraying system will gather at one end of the bottom of the landslide model to form a water collection area.

[0013] A further improvement of the landslide simulation experimental device of the present invention is that the water level control and spraying system further comprises: a water level gauge, which is vertically arranged in the experimental box near the water collection area and is used to mark water level changes.

[0014] A further improvement of the landslide simulation experimental device of the present invention is that the water level control and spraying system further comprises: a water reservoir, which is arranged on the top of the experimental box and is used to store water required for the experiment.

[0018] A further improvement of the landslide simulation experimental device of the present invention is that the water level control and spraying system further includes: a pore water pressure detection module, which is buried inside the landslide model and is used to detect the pore water pressure inside the landslide model.

[0019] A further improvement of the landslide simulation experimental device of the present invention is that the water level control and spraying system also includes a spray switch arranged outside the experimental box, and the spray switch is respectively connected to the plurality of spray heads for controlling the start and stop of the spray heads.
