Abstract: Luohangtan landslide is one of the important landslides in Gushan hydropower station of Hanjiang, it is an accumulational landslide of collapsing soil, the volume is about 70 × 104 m3, it is a medium-sized landslide. According to a field survey, preliminary analysis shows landslides are stable for current state overall. For status quo，heavy rain and reservoir impoundment, the landslide stability is calculated, the results show that：in status quo conditions, the landslide is stable; under heavy rain and reservoir impoundment conditions, landslides on both sides are in poor stability, the landslide stability of middle part is better, however, the instability of landslides on both sides is bad for the stability of middle part. Landslide failure is more harmful to the project; using lardslide treatment combining with filling materials for cofferdam as removal measure is proposed

Key words: Luohangtan landslide, basic characteristics, formation mechanism, stability analysis, measures, Gushan hydropower station
