Size, makes air pocket analogue technique more accurate；Wax stone be heated easy melt, fusing point is far below resin material, and not with resin material
Material reacts, and is easy to for wax to be heated into sucking-off after liquid.
5th, the feasibility analysis of the inventive method is as follows：
To simulate true rock mass using after K39 resin forming.But resin (can be promoted due to each additive during making
Enter agent, IPD and defoamer) composition different so that the rock sample making has different physical propertys, including bullet
Property modulus, Poisson's ratio and peak value bearing capacity.Counted according to experimental study, the step 4 in prepared rock sample) indication answer
The impact to rock mass for the content of conjunction curing agent is maximum.Therefore, different quality content curing agent has been made using above-mentioned preparation method
Rock sample, then uniaxial compression test is carried out to it, result of the test as Figure 1-Figure 4,
Fig. 1 is with maximum displacement figure under different composite curing agent mass content；

Fig. 4 is with Poisson's ratio figure under different composite curing agent mass content.
In substantive markets, corresponding handicraft or machine tool are made to K39 resin, carry out proportioning combination and add examination
It is desirable to the weight percent hundred of the relative crystal resin of curing agent is 1% when agent.But the springform of the rock sample thus making
Amount is little, and deformation is big.During carrying out uniaxial compression test, often bearing capacity reach 120kN about when also completely not broken
Bad, but displacement deformation amount beyond can test scope it is clear that being the basic physical phenomenon not meeting true rock sample.Adjusted hard
After the degree of agent, hardness is remarkably reinforced, and deformation also accordingly diminishes, and demonstrate its be can simulate completely true
Real rock sample.Be can be seen that by Fig. 1-Fig. 4, when hardening agent content is 1%, carrying force intensity can reach 120kN, but deformation journey
Degree has also reached 4.2mm, and energy is fully converted to elasticity and can be able to be lost with other；Additionally, with the reduction of hardening agent content,
Although in manufacturing process, resin becomes that rock sample hardening by cooling process time is longer, and elastic modelling quantity is sustainable growth, and displacement is
Aximal deformation value reduces, and its fragility is bigger, substantially similar with true rock.Illustrate curing agent 0.2% about resin rock sample complete
Bearing capacity entirely can be simulated in 50kN, elastic modelling quantity in 2.2Gpa about rock.
Fig. 5 is length travel rate of deformation figure；Fig. 6 is lateral displacement rate of deformation figure；Fig. 7 is Fig. 5, corresponding mutation in 6
Point explosion views, can be seen that 1. process 2. from Fig. 5-Fig. 7 and can be seen that the development that there occurs microfissure above bubble；②—
3. all there occurs around the whole bubble of process that shade changes, illustrate that in prerupture 0.2s, the crack around bubble is substantially all
There occurs extension and insertion, just can make visually the appearance of apparently shadow surface；3. process crack development 4.
Completely and Displacement Saltation occurs；4. process 6. is to continue to extend along failure mechanics under continuing to loading condition.
