Detailed description of the invention
As Fig. 1,2, the carrier of the present invention has the cavity of cuboid shape, and the rock test piece of cuboid shape is fixed on
In this cavity, between every one side and the cavity cavity wall relative with this side of described rock test piece, it is provided with flexible capsule 2, each
Flexible capsule is provided with at least one conduit 21, and highly pressurised liquid enters in flexible capsule by this conduit, loads rock test piece,
Rock test piece is made to produce the high-ground stress of simulation.
In conjunction with Fig. 2, carrier 1 all uses 35CrMo material to make, it is possible to bearing the internal 0 ~ 10Mpa pressure of capsule 2
In the case of, amount of plastic deformation is the least, thus the precision of test data is formed without impact.This main carrier will be by pedestal 1, carrying
Frame 12, base plate 16, side plate 13 and top board 14 form.Pedestal 11 level frame sets on the ground, and bearing frame 12 is a cuboid
Framework, this framework straddles on the base 11, and bottom is connected with pedestal 11 by connecting hole and the bolt and nut securing member arranged.
Base plate 16 is placed on the pedestal 11 that bearing frame 12 is straddled, and enters above-mentioned cavity for ease of rock test piece, and base plate 16 is to slide
Connect on the base 11, outside so extensible cavity of base plate 16, in order to test specimen is placed, after test specimen is put into base plate 16 more dynamicly
By slipping in described cavity of base plate 15 opposite base 11.The present embodiment is to arrange guide rail (not shown) on pedestal,
And corresponding roller (not shown) is set in the downside of base plate 16, base plate passes through roller scrolling realization on the guide rail above-mentioned end
Slip on plate opposite base.
Four vertical side of bearing frame 12 and the horizontal top surface at top are covered by side plate 13 and top board 14 respectively, thus push up
The cavity of above-mentioned placement rock test piece mutually crowded around into by plate, side plate with base plate.
For the present embodiment, such as Fig. 1, straddling with bearing frame, on the perpendicular side plate in direction 13, behaviour can be set
Make hole 4, it is simple to expand the installation settings of the drilling tool 6 of excavation simulation.Arrange blast load simulation to occur in the outside of top board simultaneously
Device 3.In theory, handle hole 4 can be arranged on four vertical side of bearing frame 12 and take up an official post on side plate, and blast load simulation
Generator 3 can be arranged on the either side of bearing frame 12.
Above-mentioned flexible capsule 2 uses the pressure rubber of high intensity to make, carrier 1 support under can bearing pressure 0 ~ 15Mpa,
And can deform with the shape of test specimen so that it is can the most snugly touch with test specimen, preferably to simulate the stress of deep rock mass
State.In conjunction with Fig. 2, flexible capsule 2 is that the size of rectangular-shaped its thickness direction of bag is much smaller than itself and the width of test specimen contact surface
Degree or the size of length direction, conduit 21 is arranged on the side of this capsule and cavity cavity wall opposite side, in order to from forming chamber
Draw on the side plate of wall or top board or base plate.Being filled with in flexible capsule 2, highly pressurised liquid (oily) is front, needs its evacuation,
Bleed for convenience, be also provided with another root conduit 21 and discharged by this exhaust tube as exhaust tube, the gas in flexible capsule.
Conduit 21 in flexible capsule 2 is from forming the side plate of cavity wall, top board, base plate extraction, with by corresponding pipeline respectively
It is connected with Hydraulic Station and air compression station.For being all respectively equipped with fairlead on this side plate, top board or base plate, can be found in Fig. 2.
