Long-term triaxial testing of Opalinus Clay, P-orientation

This data set describes a long-term (> 2 yr) rock mechanics experiment of Opalinus Clay using a triaxial apparatus. The sample is consolidated and fully saturated. The bedding orientation is parallel to the main axis of the sample (P-orientation). Confining stress, axial stress and pore pressure are changed multiple times in order to investigate dilatancy, pressure diffusion coefficients and Young's modulus.本数据集描述了一项采用三轴试验机开展的奥帕林努斯黏土（Opalinus Clay）长期（>2年）岩石力学试验。试样经固结且完全饱和，其层理方向与试样主轴平行（P型定向）。试验过程中多次调整围压、轴压及孔隙压力，以研究扩容特性、压力扩散系数与杨氏模量。
