    Liquefaction test and seismic load simulation of saturated sand subgrade with different salt contents by Lei Zhang, Lei Zhang, Lei Zhang, Hongxia Qiao, HongZhuang Shi, Weizhong Ma, Shanglin Song, Hanghang Wang

    Published 2023-12-01
    “…The results show that the maximum value of axial stress of saturated sand decreases with the increase of salt content; the load vibration times of saline saturated sand reaching the initial liquefaction state are more than that of common saturated sand; the higher the salt content, the weaker the liquefaction resistance of saturated sand; when the pore pressure ratio coefficient reaches 1, the axial double amplitude strain εd of the soil also reaches 5%, and the soil reaches the initial liquefaction state; the area of shear stress and strain hysteresis curve increases with vibration load, and the elastic modulus decreases gradually; the shear dilation and compaction effects occur in each hysteresis cycle, and the former is greater than the latter, the research results have guiding significance for similar studies in highly saline saturated sand areas.…”
