- Abstract
This paper explores the physical and mechanical properties of interface transition zone between loess and paleosol. Four samples were collected from Jingyang in the southeast of the Chinese Loess Plateau, and subjected to site and lab shear tests, aiming to disclose the shear behavior of interface transition zone, which contains landslide hazards. The results show that the strength parameters of loess decreased by nearly 2/3 (a 18.8kPa drop in C value and an 8.7° decrease in f value), and the interfacial transition zone and paleosol decreased by less than 10% from the natural state to the saturated state. This means the interfacial transition zone is a natural slip bed of landslide.
