Ultrasonic vibrating vacuum preloading test method

The invention relates to an ultrasonic vibrating vacuum preloading test method. A system used by the ultrasonic vibrating vacuum preloading test method comprises a model box for accommodating a test soil sample, wherein water draining plates are inserted into the test soil sample; the water draining plates are connected with a hose through water draining plate-steel wire hose adapters; the hose isconnected with a water and gas separating tank equipped with a vacuum pressure gauge; the water and gas separating tank is connected with a vacuum pump through a hose and a control valve; the water draining plates are ultrasonic vibrating water draining plates; ultrasonic transducers connected with an ultrasonic generator are fixed to the water draining plates. By the ultrasonic vibrating vacuumpreloading test method, clogging of the water draining plates can be effectively prevented, the consolidation rate of vacuum preloading drainage is increased, the dissipation of pore water pressure isaccelerated, and the soil
