Experimental test system and method of disturbing creep of rock under pressure action of infiltration water

Abstract

The invention discloses an experimental test system and method of disturbing creep of rock under pressure action of infiltration water. According to the system, a first support pillar is fixedly arranged on a base, first and second reinforcing beams are pivoted to the first support pillar, a movable support is arranged on the second reinforcing beam and is contacted with the first reinforcing beam, one end of the first reinforcing beam is fixedly connected with a weight holder and a vibrator, a frequency modulator is externally connected with the vibrator, the vibrator produces vibration withdifferent amplitude values and different frequencies through modulation of the frequency modulator, and axial disturbance with different amplitude values and different frequencies is further producedfor a test piece; impact disturbance of different strengths is realized through free falling bodies of weights in different masses from different heights; a creep loading test can be realized by increasing or decreasing weights on the weight holder; different confining pressure and different seepage water pressure can be loaded to the test piece; experimental test of creep of the rock under the conditions of different axial pressure, different confining pressure, different seepage water pressure and different disturbing characteristics is realized, and the creep characteristic of the rock under the complicated condition can be better researched.

Description

Technical field: [0001] The invention relates to the technical field of rock uniaxial and triaxial creep experiment testing, in particular to a rock disturbance creep experiment testing system and method under the action of seepage water pressure. Background technique: [0002] There are more and more mines above the kilometer level in my country. With the gradual development of resource mining to the deep, the mining depth continues to increase, and the environment for the occurrence of deep surrounding rocks is becoming more and more complex, especially the deep rock mass is in the "three highs and one disturbance" Under the mechanical environment, the roadway deformation and damage are more serious. The roadway deformation is mainly creep, and the stress state of the surrounding rock in the deep shaft is close to the rock strength limit. , the water pressure is increasing, and the problem of water damage in deep mining is becoming more and more serious. Some mines cannot ...
