Abstract: On March 6, 2016, a small-scale loess landslide with an estimated volume of 2×104 m3 occurred in the Jiangliu village in the southern tableland of Jingyang county. Based on the site geological investigation, combined with the low-altitude photogrammetry and 3D laser scanning, the basic characteristics and the failure mechanism of the landslide is analyzed. The results show that the agricultural irrigation are the fundamental conditions for the landslide. The softening effect of water logged zone at the foot of slope, a shorter distance with the irrigation canal, and the spring thaw of the frozen loess directly caused the landslide. The cushion effect and guided function of the saturated loess at the bottom of the deposition are the main factor for the remote movement of the landslide. This kind of landslides frequently occurs in recent years. It is the main type of loess landslide evolution at its late stage. This kind of landslides is special and usual and they are worthy of examining a further study.
