| Summary: | In order to study the relationship of the damage evolution and acoustic emission fractal of
marble under uniaxial compressive load, damage evolution and acoustic emission(AE) character of
marble under uniaxial compression are studied using MTS815.04 servo-controlled rock mechanical
test system and AEwinE1.86 system. The relationship curves of damage variable and correlation
dimension is analyzed. The results show that the value of correlation dimension is great and there are
few feature points in the stage of initial damage, and then the values of correlation dimension
drastically change and reduce as a whole and feature points increase rapidly in the stage of damage
stable evolution and development, finally the values of correlation dimension reduce to the minimum
and feature points are intensive in the stage of damage accelerating development. The phenomenon
that the value of correlation dimension appear choppy greatly reduce can be thought failure precursor
of rock and that the values of correlation dimension reduce to the minimum can be thought the
damage of rock basically completed. |
