EXPERIMENTAL STUDY AND DETECTION ANALYSIS OF MECHANICAL PROPERTIES VARIABILITY OF ROCK MASS IN EXCAVATION DISTURBANCE

Abstract
The change of resistivity of rock during its damage process is studied by uniaxial cyclic loading and unloading test.The variation rules of rock resistivity,elastic modulus and compression strength in the damage process is found out that it accords logarithmic mathematical model.So the rock damage variable can be expressed in resistivity change.The results of marble triaxial compression test show that the relationship between rock elastic...
