    Abstract
  • Under the actual rainfall infiltration condition, the research on the shear strength evolution law of Xiashu loess is insufficient. According to the change of water contents under the condition of rainfall infiltration obtained by automatic monitoring, the experimental research on the shear strength evolution law of Xiashu loess under the condition of rainfall infiltration was carried out in two typical slopes in Zhenjiang. The results show that the shear strength of Xiashu loess is greatly affected by the water content, and the strength characteristics of Xiashu loess are different near limit water content. With the increase of water contents, the cohesion of Xiashu loess decreases slightly at first, then decreases sharply, finally decreases slightly and remains stable. With the increase of water contents, the internal friction angle of Xiashu loess decreases sharply at first, then decreases slightly and finally remains stable. The research results can provide a theoretical basis for the protection and treatment of Xiashu loess slope, and have practical engineering significance.
