Water level rising and falling device of geotechnical centrifuge
The invention discloses a water level rising and falling device of a geotechnical centrifuge. The water level rising and falling device comprises a model box installed in a hanging basket of the centrifuge. A model base plate is arranged at the bottom of the model box and supported by stand columns located below the model base plate. A gap is reserved between one lateral face of the model base plate and the corresponding side wall of the model box. The bottom of a test water tank is connected with the bottom of the model box through connecting pipes. An air inlet pipe is connected to the top of the test water tank. A method for simulating rising and falling of the water level through the water level rising and falling device when the geotechnical centrifuge runs includes the steps that high-pressure air is led into the test water tank, water is pressed into the model box, and the pressure of the high-pressure air is controlled to achieve stable and repeated rising and stable and repeated falling of the water level in the model box. According to the water level rising and falling device, rising and falling of the water level are achieved through the characteristics that air pressure transmission is rapid and almost free of gravity influences, and can be carried out under the condition that the centrifuge does not stop; influences, caused by a high centrifuge field generated by the geotechnical centrifuge, on rising and falling of the water level can be avoided, the structure is simple, and operation is convenient.
