Description
Technical field
A kind of vertical compression ancillary test device is the utility model is related to, is referred in particular in Geotechnical Engineering field by servo
Forcing press carries out the ancillary test device of the vertical compression test of Rock And Soil, i.e. the adjustable Rock And Soil of lateral spacing condition vertically compresses auxiliary
Help experimental rig.
Background technology
For the Rock And Soil during military service, the presence of the difference of confined pressure state, especially free face can influence its power
Learn performance.According to position of the Rock And Soil in building structure or nature, and after considering the quantity and its relative position of free face
Compression operating mode can be reduced to six kinds of situations, be respectively：1. without lateral spacing compression operating mode, such as common rocks cylinder；2. one side lateral spacing
Compression operating mode, if any the rock cylinder in the face of support；3. proximal surface lateral spacing compression operating mode, the compression rock mass protruded such as corner；4. opposite
Lateral spacing compression operating mode, such as rock strip footing；5. three surface sides limit compression operating mode, as high cutting-slope rock faces the rock mass at sky position；⑥
Completely（On four sides）Lateral spacing compression operating mode, such as deep rock mass.All kinds of compression operating modes cause to answer during its military service because confined pressure is different
The power regularity of distribution differs, and bearing capacity has very big difference.
At present, three kinds of indoor and outdoor tests methods below generally use deform and strong to realize to Rock And Soil under various operating modes
The research of degree, method one：Without lateral spacing uniaxial compression test, this method is by cylinder and the variously-shaped rock sample or soil such as corner post shape
Sample is directly placed in press device pressurization storehouse, and by being axially further applied load and being tested, under the operating mode, sample lateral displacement is not
It is constrained, cause sample compression failure eventually through axial pressure；Method two：Common triaxial compression test, also referred to as false three axles
Cylindrical rock sample is placed in the container with hydraulic pressure by compression test, this method, applies constant enclose to cylindrical Rock And Soil sample
Apply axial compressive force after pressure again, until failure by shear occurs；Method three：True triaxial compression test, this method use direct prism
Body or cube rock sample, the backing plate for eliminating end-face friction is accompanied by, applies pressure of different sizes from tri- directions of X, Y, Z, to survey
Determine deformation and the strength characteristic of sample.
For method one, only stress in its axial direction, and its horizontal direction displacement is unrestricted, therefore nothing can only be simulated
The compression operating mode of lateral spacing；To second of test method, ordinary triaxial test intermediate principal stress and minor principal stress are equal（σ2=σ3）, it is exactly
Sample is set to be tested under axisymmetric stress state, this obviously can not be applied to all operating modes, because actual Geotechnical Environment
In, the big principal stress, intermediate principal stress and minor principal stress suffered by native unit are often unequal, therefore can not simulate actual compression
The stress-strain relation of Rock And Soil under operating mode；Though the true triaxial compression test in method three is on the basis of false triaxial compression test
Improve to some extent, rock sample is in three principal stresses unequal（That is σ1>σ2>σ3）Stress assembled state under, but still not
The actual military service operating modes such as unilateral limited, adjacent side lateral spacing can be simulated, while pole is made in the presence of true triaxial test machine used in this method
The shortcomings of its costliness, high energy consumption, complex operation.
