Description
Technical field
This utility model is related to a kind of specimen holder of rock mechanics true triaxial test, for energetic disturbance type rock burst simulation
True triaxial test, belong to rock mechanics experiment technical field.
Background technology
In recent years, mine both domestic and external, Hydraulic and Hydro-Power Engineering, traffic tunnel, national defence protection works, nuke rubbish bury etc. ground
Lower engineering constantly extends to deep.In deep rock mass digging process, it is commonly encountered rock burst hazard problem.Rock burst refers to poly- in rock mass
Long-pending elastic deformation potential energy is fierce suddenly under the conditions of excavation disturbance to be discharged thus leading to the explosion of rock mass fragment and with certain initial velocity
Spend the geological disaster phenomenon ejecting.Rock burst can be divided into strain type rock burst and the big type of energetic disturbance type rock burst two.Strain type
Rock burst refers to that high-ground stress rock mass leads to rock mass to be put aside due to the bearing capacity that the stress concentration that excavation off-load causes exceedes country rock
The rock burst that drastically discharges of elastic strain energy.Energetic disturbance type rock burst refers to excavate front tectonic movement or tangentially should after excavating
Power concentration acts on and stores the rock mass of great number of elastic strain energy in the exterior power disturbance such as engineering explosion, mechanical vibration, seismic wave
The rock burst of the lower triggering of effect.Energetic disturbance type rock burst has three features such as randomness, hysteresis quality and emergentness, can lead
Cause the delay of the injures and deaths of personnel, the breaking-up of excavation equipment and duration in the underground rock engineering construction of deep, thus causing great warp
Ji loss.
Currently, the genesis mechanism of energetic disturbance type rock burst is unclear, leads to Prediction for Rock Burst problem to become worldwide difficulty
Topic, in the urgent need to disclosing its genesis mechanism by indoor rock mechanics experiment.With routines such as single shaft, normal triaxial, true triaxial
Test compares it is considered to the true triaxial test that one side faces sky can the neighbouring country rock of free face more preferably after simulation underground cavern excavation
The stress of unit, and can achieve the observation of rock burst fragment ejection process, the type test will become rock burst laboratory test
A kind of development trend.
After underground cavern excavation, free face in rock mass, and near free face, the stress of country rock unit is from three-dimensional six
Face stress state is converted into three-dimensional five face stress state, and will lead to when the tangential stress being gradually increased exceedes Rock Bearing Capacity should
The generation of modification rock burst, when tangential stress is less than but during close to Rock Bearing Capacity, energetic disturbance can be triggered by stress wave
Energetic disturbance type rock burst.When rock burst occurs, rock fragment is fiercely launched into hole by free face.Therefore, compress with true triaxial
Cube rock sample is carried out three-dimensional hexahedro encirclement difference using fixture by test, and true triaxial rockburst test needs rock sample in three received strength
Under conditions of a free face at least occurs.
The patent of Application No. cn201110099596.1 describes a kind of true triaxial test rock sample device of cyclic skeleton,
This fixture is applied to the loading of oil pressure loading tester it is impossible to be applied to pressure-loaded of rigidly cutting somebody's hair.
The patent of Application No. cn201310178266.0 describes a kind of fixture dress carrying out true triaxial mechanical test
Put, this model cannot be realized one side and face sky, three-dimensional five face stress and one disturbing to the power under the basic stress condition such as disturbance load
The simulation of ejector half rock burst.In order to reproduce energetic disturbance rock burst indoors using true triaxial test machine, need to develop new rock sample
Fixture, to realize keeping one side to face sky, three-dimensional five face loading axial force and apply true under three specific conditions such as disturbance load
Three axle rock burst tests.
