Abstract:: Landslide is one of important geohazards in Three Gorges Reservoir, which was affected by many factors. Taking Shuinichang landslide for example, the authors adopted automated remote monitoring system to monitor rainfall and water level fluctuation, analyze the relationship between rainfall & water level fluctuation and landslide deformation. It shows that some serious deformation period is resulted from rainfall & water level fluctuation. Rainfall & water level fluctuations are the main factors affecting landslide stability. The influence of rainfall on landslide deformation presents some hysteresis effect, and the hysteresis period lasts 7～15 days. Monitored data also shows that this landslide is still in the deformed period, which is rotated to SE direction, but its trend slows slowness down. This monitoring system in the landslide can describe the movement of landslide quantitatively, which shows important guide signification on other similar landslides in Three Gorges Reservoir.
