Geotechnical Engineering Testing System

Load Frame Integrated Model Box

The open style model box is generally used to simulate the boundary conditions of underground or shallow surface underground engineering. The ground stress of deep underground projects such as mines and tunnels will far exceed the carrying capacity of the open style model box. In order to simulate the ground stress of about 1-10 MPa, Generally, the model box and the load frame adopt an integrated design, which is called a load frame integrated model box.

The picture shows the load frame integrated model box design of the three-dimensional physical model test system for the excavation process of large-scale deep engineering. The system can be used to simulate the formation pressure, realize the three-dimensional loading of the formation stress in two horizontal directions that are perpendicular to each other, and simulate the interaction of various engineering structures such as roadways, tunnels, subways, chambers, and small-scale slopes mechanical effect.
