摘要

本实验研究以液体传压方式与圆体传压方式对砂岩和工程塑料进行了0—3.72GPa 压力的准静水压状态下的体积应变测量

以液体传压的实验数据对固体传压的较低压部分的实验数据进行标定

得到了较为准确的实验结果。对固体传压实验中摩擦力的影响作了较为详细的讨论

给出了误差范围。最后通过对实验结果的分析

提出了固体传压试验中传压介质的选择标准。

Abstract

The volumetric strain observation of sandstone and plastics under quasi-hydrostatic pressure with 0-3.72GPa is presented in the paper. There are two ways of transmitting pressure

liquid and solid ones. The observes data with low pressure from solid transmitting way are checked by that from liquid one

which leads correct results. The effect of friction of transmitting medium on inner pressure in solid transmitting test is discussed in detail

and the extent of error is given. With analyzing experiment results

the option standard of transmitting medium for the test of solid transmitting pressure is obtained.
