2018, Huang is of heap of stone etc. to disclose a kind of simulator for slope model test, including transverse moving structure, vertical shift knot
Structure, Precipitation Structure etc., the rainfall in analog Landslide Model different direction, different directions.
It is concentrated mainly on rock material simulation aspect above with respect to landslide physical simulation experiment research, and is achieved compared with great achievement
Function, theoretical and application are also more mature；But the object of slope model test is in addition to rock landslip, and there are also soil property, gravelly soil, heaps
Types, the especially talus slides containing weak intercalated layer such as product body landslide are more common, are directed to heap containing weak intercalated layer both at home and abroad at present

It is changing, is causing Geotechnical Centrifugal Model Test that cannot obtain the uniform field of force, this and engineering physical presence larger difference；It fed
The Coriolis acceleration generated in journey can also cause centrifugal test model error, the promotion of rotation speed and decrease up to stopping and all need
The regular hour is wanted, field of force variation caused so practical with engineering is also not to be consistent, and is made to the reliability of test result
At very big influence.
