Description
The present invention relates to a kind of indoor sample preparation devices rupturing rock sample based on slurries reparation, belong to Geotechnical Engineering neck
Domain.
Background technology
It is well known that there is a large amount of structural plane in natural rock mass, structural plane destroys the integrality of rock mass and continuous
Property, control the mechanical property of rock mass.In engineering, cement grout is commonly used to reinforce rock joint, it is desirable to increase rock joint
Intensity.After cement grout is filled into joint fissure and condenses, a kind of complex structure body is formed, deformation, strength characteristics are both by two
The mechanical property control of kind material itself, and influenced by joint surface appearance feature, while also by glue between two kinds of materials
The effect of power is tied, this just determines the complexity of grouting joint mechanical property.Therefore, it is necessary to carry out detailed laboratory test research
Slurries reparation ruptures the repairing effect and the mechanism of action of rock sample.The particular problem of research includes：Whether intensity is true after the grouting of joint
Just it is improvedThe amplitude that intensity improves is muchIntensity and the mechanical property of grouting material and joint palisades itself have after grouting
What relationshipWhat relationship is intensity have with grouting layer thickness after grouting
Currently, domestic as follows about the repairing effect of slurries reparation rupture rock sample and the present Research of the mechanism of action：
(1) rock-soil mechanics (2011, volume 32, the 9th phase) " experimental study of rock structural face grouting and reinforcing shearing-resistance characteristic "
The rock sample structural plane slip casting reparation that uniaxial compression test is formed in article, then shearing test is carried out to the rock sample of slurries reparation,
Influence of the slip casting to mechanics parameters such as the strength and stiffness of rock sample structural plane is analyzed, to have studied rock sample structural plane
Grouting consolidation effect.
(2) " buried vertical panel splits hole in Structure Rock to Wuhan University Journal (engineering version) (2012, volume 45, the 5th phase)
In room failure mechanism of stability " article to grouting zigzag single-unit reason in the case that compression shear deformation characteristic and peak shear strength into
Numerical experimentation research is gone, emphasis is strong to grouting joint peak value shearing resistance to factors such as grouting packing density, Undulating angle and normal stresses
The influence of degree is analyzed.
(3) " grouting joint press-shear deformation, intensity are special for Wuhan University Journal (engineering version) (2014, volume 47, the 4th phase)
By carrying out cement grout consolidation process to the joint test specimen manually cleaved in point and failure mechanism experiment " paper, and carry out one
Serial interior compression-shear test analyzes packing density and normal stress to the deformation at joint of being in the milk, the affecting laws of strength characteristics.
Since the indoor sample preparation for rupturing rock sample based on slurries reparation level is very simple, and repairs triaxial compressions based on slurries and incline
Tiltedly the indoor sample preparation of rupture rock sample is more difficult, at present also without such device, so it is previous only by carry out numerical experimentation and
Slurries repairing effect and the mechanism of action are studied to the shearing test of the rupture rock sample based on slurries reparation.However, deep rock mass
In the comprehensive function of the multiple factors disturbed in crustal stress and engineering construction, mechanical characteristic is in three-dimensional stress state.Therefore,
Only slurries repairing effect and the mechanism of action of the rupture rock sample of research slurries reparation manually cleaved under shearing condition are not
Completely, the slurries reparation with greater need for the rupture rock sample formed under the three-dimensional stress state of slurries reparation under three-dimensional stress state
Effect and the mechanism of action are studied.
