| 摘 要： | 本构试验是岩石力学的基础 ,本构试验失真就会导致岩石力学的分析和计算失效。目前地下工程围岩的分析计算与实际的差异较为显著 ,本文通过机理分析 ,阐述了本构试验失真的原因 ,通过“散开”和“挤出”试验 ,图示了失真的过程 ,最后依据试验数据分别计算了岩性参数 ,说明了两者之间的显著差异。

| Abstract: | Constitutive experiment is foundamental to rock mechanics.The analysis and calculation will be wrong if the constitutive experiment is distorted. The difference between calculated and measured results is obvious in underground engineering. Based on the analysis of mechanism and experiments, the reason of distortion is presented,and the distortion course is shown with pictures.Mechanical parameters are calculated,and it has proved that the constitutive experiment is distorted. |

| Keywords: | constitutive experiment distortion peaking phase post-peaking phase |
