[0002] The earthquake simulation shaking table test can realize various forms of seismic wave input and simulate the whole process of several earthquakes of different magnitudes. It is the most direct indoor test to study the seismic response law and failure mechanism of slopes, and can restore the earthquake process more realistically. Due to its many advantages such as high restoration degree and strong reliability, a large number of scholars at home and abroad have adopted the shaking table test to study the seismic performance and seismic response of slopes. The design and production of the model box is a very important part of the slope shaking table test, which plays a vital role in the accuracy of the conclusion of the dynamic response of the real slope under the action of earthquake. Different types of rigid model boxes have revealed a large number of laws of the dynamic response of slopes under earthquake excitation. At present, the layered slope production in the shaking table test usually adopts the layer-by-layer compaction method. This method will cause the slope density to gradually increase from the top to the bottom, and the overall density of the slope is inconsistent, which cannot simulate the seismic dynamic response of the real slope. Therefore, in order to better study this problem, a device that can both stack layered slopes and ensure their consistent density is needed.
