3rd, operation principle
1）Layering loads soil sample 21 in two-dimensional ultrasound wave transducer 122, and the water surface is higher than the top surface of soil sample 21 when loading every time
1-2cm, it is ensured that the soil sample 21 of filling is saturation soil sample；Meanwhile in higher temperature（50℃）Lower filling soil sample 21, can so subtract
Few air enters soil sample 21 when loading；The soil sample 21 being prepared is fully saturated soil sample, and gas is free of in soil sample 21
Composition；After soil sample 21 has loaded, stainless steel top cover 32 and associated pipe are installed, regulation pressure volume controller 35 is to soil
Sample 21 applies vertical pressure.
2）The dissolved air water of certain mass is prepared by liquid air-dissolving apparatus 22, then by dissolved air water by high pressure from soil sample 21
Soil sample 21 is injected at the permeable stone 23 at top, existing air free water then passes through the high air-entry value of the bottom of soil sample 21 in such soil sample 21
Pottery clay plates 24 are discharged；The volume of injection dissolved air water will reach more than 10 times of the mesopore volume of soil sample 21, could be by soil sample 21
The air free water discharge of residual；When injecting dissolved air water to soil sample 21, the vertical pressure that soil sample 21 is subject to is kept to be filled with liquid air-dissolving
The pressure put in 22 is equal, is so avoided that in dissolved air water test error caused by gas release.
3）After the internal void of soil sample 21 is completely filled with by dissolved air water, the vertical pressure of soil sample 21 is slowly reduced step by step,
Untill the pressure of test requirements document is reached；When reducing vertical pressure step by step, the gas transition being dissolved in water in soil sample 21 is
Over-saturation state, at this moment initially form bubble in soil sample 21；It is micro- by increasing in a short time in the above-mentioned stabilization per stage pressure
Vertical pressure is measured, when the volume of soil sample 21 no longer changes, records the total variation of the volume of soil sample 21, you can obtain every stage pressure bar
Bubble volume in soil sample 21 under part；Bubble volume under the conditions of gradually record is per stage pressure, carried out by the diffusion theory of classics
Inversion Calculation, you can obtain bubble size and concentration；In bubble volume in determining soil sample, the application time of vertical pressure is necessary
It is very short, avoid bubble during applying from re-dissolving into water.
4）Vertical One-Dimensional Ultrasonic wave excitation is applied to soil sample 21 using One-Dimensional Ultrasonic wave transducer 112；Pass through two-dimensional ultrasound
Wave transducer 122 applies radial direction two-dimensional ultrasound wave excitation to soil sample 21；Under high-power ultrasonics effect, mud pore interior stream
Small complex in body is activated, and ultrasonic activation constantly quickly alternately causes cavitation bubble nuclear disruption, is produced in very short time
Localized hyperthermia and high pressure, and the shock wave and jet of accompanied by intense, so as to cause moisture and fine grain travel motion in mud；
Apply vertical consolidation pressure to soil sample 21 using pressure volume controller 35 simultaneously and measure specimen deformation, the equipment can be to solid
Knot deformation, pore pressure and ultrasonic energy decay etc. are tested.
2nd, method
1. whether saturation is related to experiment success or failure for high air-entry value pottery clay plates 24 and its pipeline, therefore, before formal test, adopt
High air-entry value pottery clay plates 24 are carried out with saturation with pumping saturation, the saturation of test equipment pipeline be then utilize peristaltic pump in advance to
Inject air free water in pipeline to be rinsed, untill without bubble；
2. carrying out natural air drying to mud under the conditions of cool place, according to test requirements document, the air free water of certain mass is added
In mud air-dry sample；
3. the mud sample after water will be added to be layered filling soil sample 21 in two-dimensional ultrasound wave transducer 122, every layer is consolidated
Same number is to ensure the overall uniformity of soil sample 21, and the water surface is higher than the top surface 1-2cm of soil sample 21 when loading every time, it is ensured that filling
21 be saturation soil sample；Meanwhile temperature control equipment 26 is adjusted, soil sample 21 is loaded at relatively high temperatures, can so reduce air
Enter soil sample 21 when loading；Mud composition can be had an impact however, temperature is too high, tentatively draft and being filled out under the conditions of 50 DEG C
Dress；Therefore, the saturation soil sample 21 of certain density just can be prepared by above-mentioned steps, and gas componant is free of in soil sample 21；
