Effects of cyclic loading on the rheological properties of sandstones

Popis výsledku v původním jazyce

Research into the rheological properties of rocks is mostly done under static loading. In nature, however, rocks are also often subjected to cyclic (vibration) loading as a result of vibrations from traffic or the propagation of seismic waves due to, forexample, earthquakes, rock bursts, blasting operations and such like. On this account, the research presented is focused on the study of rheological rock properties during vibration (cyclic) loading. The tests of the rheological properties of a cyclic load were conducted both in creep regime and in relaxation regime, at various levels of average load or strain and for various parameters of vibration (frequency, amplitude). The measured values of different parameter settings were compared and evaluatedso that it was possible to set the dependence of cyclical rock loading in the rheological regime. The submitted paper presents some results of the laboratory tests on the time-dependent behaviour of three types of sandstone.
