Problems solved by technology

[0002] In the process of landslide model test, the landslide sliding is simulated by using manual stacking or hydraulic device to apply landslide thrust. The landslide model takes a long time to produce sliding, the labor cost is high, and the soil behind the pile changes slowly and is difficult to observe.
During the loading process of the model, the soil material of the landslide model is easy to be compacted and compacted, which will cause changes in the soil parameters of the test and further affect the results of the model test. Loading on the top of the landslide requires high mechanical properties of the device carrying the landslide, and the cost is very high. Nowadays, a simple and quick device and method for obtaining the test data of the landslide retaining structure and recording the landslide test data in detail is needed.
