Problems solved by technology

[0004] ① Cannot simulate the effect of seasonal freezing and thawing on slope landslides, slope or landslide instability and damage under the action of water
[0005] ② Using the rigid plate set on the top of the slope to simulate the actual gravity load will cause the load to be redistributed and there will be simulation distortion
In the landslide simulation test, the rigid plate cannot deform correspondingly with the deformation of the model slope, which will lead to significant load distribution, thereby affecting the test results; in order to avoid simulation distortion, the current part of the loading method is complex and expensive to control. high
