Majiayu Village in Laiwu District is constructing an exhibition and sales greenhouse on the mountain behind the village. Due to improper construction，landslide often occures on the surface of the exhibition and sales greenhouse and the platform is piled up outside the site. In order to study the deformation characteristics，causes，and stability of landslide bodies， a detailed investigation of the landslide site was conducted，and the triggering factors of the landslide were evaluated and analyzed in detail. Quantitative and qualitative methods were used to study the stability. The results show that the total volume of this landslide is about 5.0 × 104 m3, and it is a small-scale sliding landslide. Under natural conditions，landslides are in a basically stable state. Under the condition of rainstorm，the stability coefficient is between 1.001-1.006，indicating that the potential landslide is in an unstable state，and sliding deformation may occur.
