A series of freezing experiments were carried out on the Qinghai silty clay using a one-dimensional soil column particle image velocimetry (PIV) system. The effects of the initial water content and temperature gradient on the frost heave of the soil column were analysed. The experimental results show that the total volumetric water content after the Qinghai silty clay freezing is much... https://www.bekindtopets.com/super-value-Crushed-Turquoise-iPhone-14-Pro-Max-MagSafe-Case-p82210-mega-value/
