Abstract: With coal mining,a large number of abandoned coal gangue be piled up to form high and steep slope. The stability of high slope is poor. Landslide could be caused by one or several of unstable factors. In this paper, the surface displacement monitoring technique of landslide is used to monitor the subgrade landslide of K13—K14 section of fuxin south ring road.And the trend of further short-term surface deformation of the landslide is studied. Studies have shown thatthe surface displacement of landslide is in the direction of 175°. At present, the slope is in uniform deformation. During the monitoring period, the surface displacement has changed greatly and the trend has been developed. Measure should be taken in a timely manner.
