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...

AI Technical Summary

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
