Data of Is the combination of linearized theoretical analysis and sand column experiment always suitable for estimating the complex effective porosity?

Sand conlumn experiments were conducted to describe time-varying pore water pressure. Height of the sand column is fixed as 50 cm and three pore water pressure transducers were deployed along the sidewall of the sand column at 46 cm, 38 cm, 30cm, 22 cm, 14cm, 6 cm below the sand surface, respectively.

为描述孔隙水压力随时间变化的情况，进行了沙柱实验。固定沙柱高度为50厘米，并在距沙面46厘米、38厘米、30厘米、22厘米、14厘米及6厘米处沿沙柱侧面布置了三个孔隙水压力传感器。
