摘要：赫章县七家湾气象站滑坡属于中型推移式滑坡，横宽为200 m，纵长为90 m，主滑向为336°，滑坡平均厚度为10 m，体积为180 000 m3。本文结合滑坡区自然环境特征，分析滑坡发育特征和变形特征，明确滑坡失稳机制，然后开展滑坡稳定性评价，提出滑坡防治方案，最终消除地质灾害风险。

Abstract： The Qijiawan Meteorological Station landslide in Hezhang County belongs to a medium-sized translational landslide， with a horizontal width of 200 m， a vertical length of 90 m， a main sliding direction of 336°， an average thickness of 10 m， and a volume of 180 000 m3. Based on the natural environmental characteristics of the landslide area， this paper analyzes the development and deformation characteristics of landslides， clarifies the mechanism of landslide instability， and then conducts landslide stability evaluation， and proposes landslide prevention and control plans， thus ultimately eliminating geological disaster risks.

Keywords： landslide; instability mechanism; developmental characteristics; deformation characteristics; prevention and control; meteorological station; Hezhang County
