Technical field
The utility model is related to hydraulic fracturing experiments technical field, specially a kind of true triaxial hydraulic fracturing experimental rig.
Background technology
True triaxial test is rock sample is in unequal (the i.e. σ 1 of three principal stresses>σ2>σ 3) stress assembled state
Under triaxial compression test.True triaxial test can study influence of the intermediate principal stress (σ 2) to rock deformation and strength characteristics.
GDS triaxial apparatus is according to mechanical test principle, it is assumed that a soil body keeps poised state, then wherein certain point must have three kinds to act on mutually
Stress on perpendicular face.A small cubes are such as cut out from upper body, it is parallel in figure such as shown in figure " principal stress and principal stress plane "
Power in tri- directions of X, Y, Z, is referred to as big principal stress σ 1, intermediate principal stress σ 2, minor principal stress σ 3.It is vertical with three principal stresses
Acting surface be referred to as big principal stress plane, intermediate principal stress face and small main stress surface.The size of three principal stress values is σ 1>σ2>σ
3, and it is orthogonal, there was only normal stress, no shear stress on principal stress plane.This stress state, can be vertical with one indoors
Cube sample is simulated.As shown in figure " the true triaxil tester schematic diagram of rigid plate structure ", it can be mutually mobile using six pieces
Rigid plate, applies σ 1, σ 2, the power of σ 3 in sample respectively, makes up to destruction, and determine the deformation and volume change in three directions of sample
Change, this experiment is referred to as true triaxial test.Sometimes need detection sample to examine under infiltration test, normal conditions not measuring
Come, it is necessary to which, by GDS triaxial apparatus, still, pure GDS triaxial apparatus does not attach water seepage tests, therefore, we design one kind
True triaxial water seepage flow test device.
It there may be crack inside stone, coal, crack can change expansion under fluid pressure, still, if outside
There is three-dimensional pressure in portion, then change of the crack under fluid pressure is different again, and in the market also has similar device, but
It is that the device that it scans crack is fixed, not comprehensive enough image is scanned, therefore, we design a kind of true triaxial hydraulic fracturing
Experimental rig.
