    Study of the Mechanical and Microscopic Properties of Modified Silty Clay under Freeze-Thaw Cycles by Zhou Wenjun, Wang Qingzhi, Fang Jianhong, Wang Kejin, Zhao Xiangqing

    Published 2022-01-01
    “…The shear strength of basalt fiber soil and basalt powder soil increased by 7.55% and 5.12%, respectively, compared with that of normal soil under 30 freeze-thaw cycles. Subsequently increasing of the number of freeze-thaw cycles differentially affected the cohesion and internal friction angle of normal soil and admixture soils, and these soils gradually tended to stabilize at a mechanical strength higher than the initial value. …”
