摘要:Microstructure of breeze of volcanic breccia was analyzed by scanning electron microscope, uniaxial compression and creep test were completed. Study results indicate that microstructure of breeze of volcanic breccia is compact size of the particles cemented structure. Immediate deformation of creep test specimen was above 80% of total deformation, and stress threshold existed in the rock creep. When load increased, rock creep stabilized in a short period. Under multitude stress levels, volcanic breccia showed decay creep, the deformation rate decreased with time and the deformation tended to converge finally. © 2011 IEEE.
