Abstract: A new cylinder-piston high hydrostatic testing equipment was briefly introduced. Testing procedure and measuring technique during the hydrostatic experiment were described. The properties of a marble、a silicarenite ,and a granite under hydrostatic tests were rhoroughly studied, A phase-transform in the marble under 1780 MPa was found. The effect of porosity, mineral composition ,and grain size on compressibility and residual deformation of rocks under hydrostatic pressure were examined.
