Data for the study 'Interplay of loading and adsorption controls elastic deformation of clastic and crystalline rocks'

Here we provide the experimental dataset for the study entitled, 'Interplay of loading and adsorption controls elastic deformation of clastic and crystalline rocks', prepared by Wu et al. We continuously monitor the elastic deformation of a fine-grained sandstone specimen subjected to intermittent cyclic loading at increasing ambient humidity levels (20 to 95%) approaching saturated vapor over 34 days. The dataset archived here is presented in Matlab format stored in 9 RH levels (20, 30, 40, 50, 60, 70, 80, 90, 95%) and 1 reference state of oven-dry conditions. At each humid condition, mechanical deformation data is acquired via cyclic loading cycles where axial confinement is quasi-statically increased and decreased at a constant rate of 0.5 MPa/sec up to 30 MPa. The specimen is maintained at a static seating load of 1 MPa between load cycles while mechanical deformation data is also recorded.我们在此提供由吴等学者开展的题为《载荷与吸附的相互作用调控碎屑岩与结晶岩的弹性变形》的研究配套实验数据集。本实验在34天的周期内，对经历间歇循环加载的细粒砂岩试样的弹性变形进行连续监测，实验环境的相对湿度（relative humidity, RH）从20%逐步提升至接近饱和蒸汽的95%。本次归档的数据集以Matlab格式存储，涵盖9组相对湿度工况（20%、30%、40%、50%、60%、70%、80%、90%、95%）以及1组烘箱干燥的基准工况。在每一组湿度工况下，通过循环加载采集力学变形数据：轴向围压以0.5 MPa/秒的恒定速率准静态升降，最大围压可达30 MPa。在加载循环的间隙，试样保持1 MPa的静态预紧载荷，同时同步记录力学变形数据。
