In view of the frequent occurrence of human activity loess landslide, this paper focused on the influence of the main human activities such as irrigation, excavation, loading and mechanical vibration. The most typical mechanism of loess landslide caused by irrigation was the creep liquefaction mechanism . The main types were loess erosion slip type and plastic flow fracture type. The stress distribution of the slope was changed by slope toe excavation, the excavation destroyed the slope stability and formed the landslide hazard. When it was piled on top of loess slope, stress concentration was produced, which was disadvantageous to slope stability. When there were other inducing factors, the slope would be unstable. The effect of vibration on slope was various. However, the main factor was to reduce the strength of loess and create conditions for slope instability.
