摘要
对岩样三轴加载后保持轴向变形、降低围压的试验，可以提供轴压随围压的变化曲线，从而依据弹性本构关系确定岩石材料的泊松比。这不仅方便准确。
The experiment of confining pressure reduction is recommended for rock specimens. By keeping the axial deformation of a specimen unchanged while loading triaxially, the experiment can provide the relation between the axial stress and the confining pressure of the specimen and therefore determine the Poisson′s ratio of the material. The testing process is practical and convenient for engineering application.
