EXPERIMENTAL TEST METHOD FOR SUBCRITICAL PROPAGATION RATE OF ROCK FRACTURES BASED ON TRIAXIAL STRESS—STRAIN CURVE

CHENGDU UNIVERSITY OF TEC...

1. An experimental test method for subcritical propagation rate of rock fractures based on triaxial stress-strain curve, comprising the following steps:Step 1: preparing a test sample for experiment: drilling and cutting a core used in the experiment, and then drying the core to constant weight at a set temperature;
Step 2: putting the dried core into a GCTS triaxial rock mechanics test system, applying constant radial confining pressure to the core, and then applying axial stress in an axial direction until the core is macroscopically damaged; meanwhile, recording experimental parameters of axial stress, strain and corresponding loading time of the core throughout the loading test;
Step 3: drawing a stress-strain curve of the test core according to detection data points of axial stress and axial strain during the experimental loading process, and dividing the curve into the following five stages:
Stage I is defined as a compaction stage at which fractures in the core are closed under stress, but for the dense core, this stage is often not obvious and difficult to distinguish;
Stage II is defined as an elastic deformation stage at which pores between particles in the core are compressed and deformed but the fractures do not propagate, the core is deformed uniformly, and the stress-strain curve is approximately straight;
Stage III is defined as a stable fracture propagation stage of which a starting point corresponds to an initiation stress ?ci of the test core; when the applied stress is greater than the initiation stress, the small fractures in the core will slowly propagate with the increase of load, causing the whole rock to expand volumetrically; with further propagation, external micro-fractures in the core begin to arrange in a direction gradually; in this stage, the stress-strain curve is also approximately straight;
Stage IV is defined as an unstable fracture propagation stage of which the stress at the starting point is called fracture damage stress ?cd; from the starting point, the fracture propagation rate increases rapidly, and the state of the core changes from volume compression to volume expansion; the fractures will unstably propagate and begin to join together, eventually making the sample completely damaged; and
Stage V is defined as a post-peak deformation stage of which the starting point of this stage is a peak stress of the curve, that is, the uniaxial/triaxial compressive strength ac of the core;
Step 4: in the stress-strain curve of the test core, a starting time and a ending time of Stage III, correspond to the initiation stress ?ci and the damage stress ?cd, respectively; when the applied axial stress is greater than the fracture initiation stress ?ci, the fractures will continue to propagate slowly, but when the applied stress disappears, the fractures will stop propagating and will not damage the core macroscopically; when the applied axial stress is greater than the fracture damage stress ?cd, the fractures will enter the Stage IV;
calculating the initiation stress ?ci and the damage stress ?cd of the fracture based on the stress-strain curve of the test core, and working out the starting time Tci and the ending time Tcd of the subcritical fracture propagation corresponding to the initiation stress ?ci and the damage stress ?cd of the fracture according to the relationship between the axial stress and the time obtained by monitoring the test process; further calculating fracture lengths Cci and Ccd corresponding to the initiation stress ?ci and the damage stress ?cd of the fracture according to theory of fracture mechanics; then calculating subcritical propagation rate of the Stage III of the test core according to Formula (1):

where, u—the subcritical propagation rate of the fracture in the test core in the subcritical propagation stage, in m/s;
Tci and Tcd—the starting time and the ending time of the subcritical fracture propagation stage in the loading process of the test core, in s;
Cci and Ccd—the fracture lengths at the starting time and the ending time of the subcritical fracture propagation stage of the test core, in m;
Step 5: in the stress-strain curve of the test core, the fractures do not propagate and are usually in a compressed state before the Stage III so the fracture volume strain of the core generally increases with the increase of axial strain; after entering the Stage III, the existing micro fractures in the core slowly propagate as the axial stress increases, resulting in the overall volume expansion of the core, and the volume of the core fractures begins to change from compression to expansion, therefore, the fracture volume strain starts to decrease with the increase of axial strain; the axial stress corresponding to the turning point where the fracture volume strain of the test core changes from increasing to decreasing with the axial strain is the fracture initiation stress ?ci of the core;
Wherein, for the test core, the total volume strain EV in the loading process is composed of an elastic volume strain and a fracture volume strain:
?v=?ev+?fv  (2);
where: ?V—the total volume strain of the test core in loading process, dimensionless;
?ev—the elastic volume strain of the test core in loading process, dimensionless;
?fv—the fracture volume strain of the test core in loading process, dimensionless;
the total volume strain of the test core satisfies the following relationship with its axial strain and radial strain:
?v=?1+2?3  (3);
where: ?1 and ?3—an axial strain and a radial strain of the test core in loading process, dimensionless, which is directly monitored in the stress-strain curve test of the core;
according to Hooke's law, the theoretical elastic volume strain of rock is calculated by the following formula:

where: ?1—the axial stress of the test core in loading process, in MPa;
?3—the radial stress under constant confining pressure applied by the test equipment to the core, in MPa;
E—the elastic modulus of the test core, in GPa;
v—a Poisson's ratio of the test core, dimensionless;
combined with Formulas (2) to (4), the fracture volume strain calculation formula of the test core is obtained as follows:

according to the calculation results, taking the axial strain as the abscissa and drawing the fracture volume strain-axial strain curve of the core in the testing process.
