О МЕХАНИЗМЕ ЯВЛЕНИЯ РЕВЕРСИВНОГО  
ДЕФОРМИРОВАНИЯ ОБРАЗЦОВ  
СИЛЬНО СЖАТЫХ ГОРНЫХ ПОРОД* 
 

На реверсивный характер линейных деформаций при сжатии образцов горных 
пород, по-видимому, впервые было обращено внимание в 1958 году в работе 
(Seldenrath & Gramberg 1958). При поиске деформационных предвестников реверсивные деформации были установлены также в работе (Tomashevskaya & 
Khamidullin 1972), где была выдвинута гипотеза дилатансионного расширения. 
Причиной реверсивного деформирования в работе (Tazhibaev 1986) были названы остаточные напряжения. Однако ни одна из рассмотренных гипотез не 
объясняет все имеющие место аномальные эффекты с единых позиций, как было показано в (Guzev & Makarov 2007).  
Ключевые слова: сжатие горных пород, линейные деформации, обратимая деформация, акустические и математические методы.

ABOUT THE MECHANISM OF A HIGH  
STRESSED ROCK SAMPLES REVERSIBLE  
DEFORMATION PHENOMENA* 
 
Attention to the reversible character of linear deformations of rock samples was presented, apparently, for the first time in (Seldenrath & Gramberg 1958). The authors 
did not research the mechanisms of the origination of the deformation anomalies, but 
already in subsequent works such attempts have begun to be undertaken. So the reversible character of the deformations of rocks was contacted with a barrel-shaped 
straining of samples at uniaxial compression (Tomashevskaya & Khamidullin 1972). 
In the works of other researchers, residual stresses were proposed in the capacity of 
reasons for deformation anomalies of various types (Tazhibaev 1986). However, these hypotheses are not supported by critics on closer examination (Guzev & Makarov 2007). In 
this paper, based on specially developed complex research methods, including on deformation, acoustical and mathematical methods, the authors analyse deformation anomalies of 
reversible types in samples of rocks at uniaxial compression, define the mechanism of their 
origin, and develop a mathematical model of the phenomenon. 
Key words: high stressed rock, linear deformations, reversible deformation, acoustical and mathematical methods.

1. Experimental research into the regularity of THE HIGH 
STRESSED rock samples FIELD near to the source of macrofailure 
Based on previous researches, a two-phase model of the macrocrack formation, consisting of a period of scattered microcracking followed by a stage of formation of the source of macrofailure and then 
macrodefect development, has been assumed (Lockner et al. 1991). 
The source field is often modelled by inhomogeneity in the form of a 
soft inclusion, calling the formation round it an area of consolidation 
at the expense of disproportionation of stress (Brace et al. 1966). 
Modern methods of researches applying servocontrolled rigid loading 
devices allow measurements to be taken directly before failure, and 
multichannel measurement systems – to research the behaviour of the 
sample as a whole, including around the site of the failure source. 
The technique of multidot deformation research of samples of 
strongly compressed rocks provides uniaxial loading of samples by 
the servocontrolled rigid loading machine MTS-816. This uses resistance strain gauges as a way of taking local measurements of deformations, both in the central part of the sample, and on its height. Thus the 
«cross» design of the resistance strain gauge allows measurements to 
be taken of both the longitudinal and lateral strains in a single position, which eliminates the possibility of the joining of individual 
measurements of the different processes. The conditions of loading, 
face conditions and sizes of the samples at compression are accepted, 
taking into account the effect of contacts of end faces with a load machine (Guzev & Makarov 2007). 
Research was conducted on samples of various rocks, including 
dacites, rhyolite, diorite, and granite-porphyry. Resistance strain 
gauges were attached at equal intervals on the whole of the sample, 
with from four to eight pairs in each row and from one (in the middle) 
to three rows in height. The special circuit design of their fastening 
has been developed to preserve the wire leading-outs on the sample. 
The readings from the resistance strain gauges were fixed by means of 
a computer program on the multichannel device UIU-2000. This research was carried out at the Geodynamics Laboratories at FEFU. 
In Fig. 1b, the schema of the sensors displacement is shown during tests. In total, 4 series on 10 samples were tested. The tests were 
carried out at uniaxial compression of samples under the multidot 
schema of measurements with from 8 to 48 sensors (Fig. 1).

Fig. 1.Schema of measurements (a, b) of a sample of dacite, source position (triangle on a, b) and change of AE intensity (c) 
The source position was fixed according to acoustic tests using a 
complex «Interjunis». The change of AE intensity during the time of 
loading is shown in Fig. 1c. It can be seen from Fig. 1c that the cracking begins at a level of loading of 224 MPa, which corresponds to the 
moment of the deflection of the stress strain curves from a linear relation. The position of the source of failure concerning pairs of deformation gauges is shown in Fig. 1a-b). 
The basic results of the tests on the laws of the deformation of 
rock samples in a prefailure state using the newest equipment can be 
reduced to the following. In a prefailure stage of loading, a series of 
anomalous deformation effects which can be used as precursors is observed. First, this flattening out of the deformation curves with reduction by it fields of modules of deformations by 1.5—3 and more times 
can be seen in Fig. 2a. It is displayed especially clearly in the field of 
the source, as shown in Fig. 2b. In this part, there are two anomalous 
deformation effects where, apart from the already noted effect of significant (repeated) decreases of the module of deformation, there are 
naturally fixed sharp augmentations of the increments of lateral deformation, which are comparable in size or even exceeding the increments of

longitudinal strain. The first anomalous effect can be considered to be 
within the limits of the model of «soft inclusion», as already mentioned above. 

2. Source model of «defective heterogeneity» with reference to 
rocks samples at axial compression 
Modelling source areas by «soft inclusion» is good knowing in geomechanics (Rice 1980). The inclusion can be ideal soft at the rock module of deformation Е = 0. It is a case of a circular hole in a semiplane with 
evenly distributed symmetrical load on a part of its border. This problem 
is considered by the author in (Makarov 2013), where the character of the 
displacements of a contour of the hole is shown as in Table 1. 
The second deformation anomaly of the source part, consisting of 
large lateral strains, as a rule, exceeding the longitudinal increments of 
deformation, indicates a shear-rupture of a developmental character in 
the mesodefect part of the source, leading to the wedge action of such 
defects (Odintsev 1996). Within the frame of the «soft inclusion» 
model, this effect cannot be considered directly, as the Poisson's ratio 
of a continuous material cannot exceed 0.5. Properties of the source 
parts of the sample are formed at the expense of defects of the shearrupture type, where the wedge action of a shift element (Odintsev 
1996) prevails. Therefore research on mechanisms of deformation 
anomalies should be divided into two stages, caused by the presence 
of two source deformation anomalies: longitudinal and across the direction of loading.

Direct overseeing by deformations of fields of rocks testify that it is 
lower and nearer to the source (Fig. 3a and 3b respectively) also. On the 
border of the source and the surrounding material, the condition of a continuity of displacements is met, so it is logical to expect deformation anomalies not only in the source area, but also in the adjoining parts of the rock.
