Description

A kind of rock disturbance generating mechanism and its relaxation-disturbance comprehensive experimental device
Technical field
The present invention relates to a kind of Rock Mechanics Test device, more particularly to a kind of rock for being used to test rock disturbance is disturbed Dynamic generating mechanism and its relaxation-disturbance comprehensive experimental device.
Background technology
Stress rheological phenomena is seen everywhere in rock mass engineering project, the excavation supporting such as some underground chambers, tunnel, tunnel Can occur rheological phenomena through rock after a while afterwards, and these rheological phenomenas usually contain the creep and relaxation of rock.It is right In the rock mass in rheology, under the disturbance of the blast load of stope, rheological effect can be further obvious, it is possible to occurs to accelerate stream Become, so as to cause the generation of mine power disaster.Particularly deeps mines underground mining is often faced with such as rock burst, gushing water, top Plate large area is pressed and the disaster such as goaf unstability, and these phenomenons are directed to rock or the long-term relaxation effect of rock mass and instantaneous Dynamic disturbances be combined problems in role.The relaxation effect of rock is a long-term process, and the dynamic such as explosion, mechanical oscillation Disturbance is a transient effects for lithological effects, and both differ larger in time scale, so few people are in test Consider influence of the collective effect to material properties of rock of both effects.Therefore, under research trends disturbing influence rock pine The permanent support of stability and design underground rock project of the relaxation effect for evaluating underground excavation space has important theory Meaning.
It is due to carry out stress relaxation examination although the importance of effect study it has been recognized that rock relaxes Need to control the strain of rock sample constant when testing, it is desirable to which experimental facilities has the performance for keeping constant displacement to load for a long time, Experimental technique difficulty is larger, and related research is less.
