In the research of geotechnical engineering problems, geotechnical engineering model tests are very effective analysis methods. Geotechnical engineering model tests are further divided into physical model tests and numerical model tests. The method is characterized in that a numerical model test is carried out according to the actual engineering situation to carry out numerical modeling analysis and obtain a series of qualitative and quantitative distribution rules of the geotechnical physical and mechanical indexes, and has the defects that the complicated actual engineering situation cannot be completely and accurately simulated, and the adopted geotechnical material constitutive model and corresponding parameters can be different from the actual situation, so that the numerical model test sometimes has wrong results, and the obtained results are often only used as qualitative references of the actual engineering. The physical model test is to scale the geotechnical structure and environment of the actual engineering according to a certain scale to carry out indoor test, does not need to carry out complicated full-scale test on site, can simulate the actual engineering relatively in preparation, can accurately set various variables influencing the geotechnical structure and environment indoors, can intuitively copy the actual engineering condition and obtain a test result, has low cost and can obtain an experimental rule consistent with the actual engineering, thereby having greater advantages than a numerical model test. Therefore, physical model test means is generally preferred in geotechnical engineering problem research.
Indoor physical model tests are typically performed in an artificially designed model box. Considering the complexity of the actual engineering, the size of the model box is sometimes required to be adjustable, and the boundary conditions can be changed; meanwhile, in some model tests, two sets of tests are required to be simultaneously carried out on the geotechnical materials and structures with different parameters so as to simultaneously carry out transverse contrastive analysis, and the model box body is required to be divisionally adjusted.
