摘要

本文介绍了内径达20毫米的活塞圆筒式高压静水压缩试验装置

该装置可在0～4500兆帕压力范围内进行P-V关系试验;描述了用该裝置进行岩石高压静水压缩试验的方法及量测技术;详细地提供了大理岩、石英砂岩、花岗岩的高压P-V关系试验结果。试验中发现大理岩在1780兆帕时发生晶相变化。

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.
