Description

Technical Field

[0001] This utility model relates to the field of geotechnical construction testing technology, specifically to a geotechnical medium model testing device. Background Technology

[0002] Geotechnical model testing refers to the creation of physical models of actual soil and rock masses and engineering structures at a certain scale under laboratory conditions, based on the principle of similarity. By applying simulated loads and environmental conditions, the deformation, failure process, and stress characteristics of the model are observed, thereby inferring the stress state and safety performance of the actual engineering project. This type of test can intuitively demonstrate the failure process of soil and rock masses and is more physically realistic than numerical simulation.

[0003] However, existing soil and rock medium model testing devices have the following problems during use: once the soil and rock are placed inside the test chamber, they are difficult to remove. After the test, manually moving the soil and rock within the chamber is cumbersome, leading to inconvenience in soil and rock handling and affecting the test operation. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content
