Long-term behaviour of a clay-bearing sandstone is investigated using elastic waves propagation coupled with strain measurements during moisture cycles. Adsorption and desorption are followed in a continuous way during several variations of relative humidity. Moisture adsorption is related to the solvation pressure and the measured elastic weakening during humidification is correlated with the clay minerals sensitivity.

黏土砂岩中水分引起的弹性减弱和波传播

使用弹性波传播结合水分循环中的应变测量研究了含粘土砂岩的长期行为。在相对湿度的几种变化过程中，以连续方式跟踪吸附和解吸。水分的吸附与溶剂化压力有关，加湿过程中测得的弹性减弱与粘土矿物的敏感性有关。
