Problems solved by technology

The existing soil displacement testing instrument is aimed at the data measurement of engineering field experiments, and the measuring range of the instrument is relatively large. It is used to directly read the experimental data in the indoor experimental environment, resulting in low test accuracy of the indoor experimental data.
The test data of the indoor model experiment is small, the test accuracy factor is ignored, and the error of the instrument leads to the large deviation between the experimental test data and the actual data or even data errors

Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] A soil displacement monitoring and acquisition device based on the indoor environment. The settlement displacement of the soil in the indoor rock and soil experiment is collected into an image by a data acquisition system composed of a camera or camera function equipment and a lighting device, and the settlement displacement images of each displacement observation point are stored. In the computer of the data receiving system, a computer program is compiled based on mathematical software to form the core of the data conversion system. The mouse picks up the pixel coordinates of the observation point and the grid line on the plexiglass plate in the displacement image displayed by the program to calculate the settlement displacement data.

[0023] In order to further realize the object of the present inve...

Description

technical field [0001] The invention belongs to the technical field of indoor experimental equipment for geotechnical engineering, and relates to a soil displacement monitoring and acquisition equipment and method based on an indoor experimental environment. Background technique [0002] Geotechnical indoor model experiment is a research method widely used in geotechnical engineering subjects. The observation of soil displacement and settlement is the main test parameter of geotechnical experiment, and the result is the main influencing factor for analyzing the stress distribution of soil and the mechanical properties of underground structures. The existing soil displacement testing instrument is aimed at the data measurement of engineering field experiments, and the measuring range of the instrument is relatively large. It is used to directly read the experimental data in the indoor experimental environment, resulting in low test accuracy of the indoor experimental data. T...
