摘要

The mechanical properties of limestone and sandstone under high temperature were investigated by the experiment device used to heat rock designed by ourselves and servo-control testing machine RMT-150C. The results show that the longitudinal wave velocity of two kinds of rocks gradually reduced with temperature increasing. The complete curve of stress and strain under uniaxial compression went through 4 stages, namely densification, elasticity, yielding and failure. They both displayed brittle fracture after reaching peak strength, with the sandstone rupturing and the limestone showing failure like a bundle of grass.
