Abstract Natural loess is a kind of kaolin wind-deposited soil.Thedifferent layers of loess experienced different overburden pressures and wetting-drying cycles, resulting in different water retention behaviors.The axis translation technique and the vapor equilibrium technique to determine the water retention behaviorof the three different sediment depth natural loess during drying and wettingprocess. In addition, the microstructure evolution experienced wetting and drying cycles also characterized by mercury intrusion porosimetry. The saturation and air entry value increased with the sediment depth increased because deeper sediment depth means lower initial void ratio. Thewaterretentioncurveshowsthatthereisalmost nohysteresis observed around the naturalsuction,and in relatively… More >
