Abstract:  “3.28” landslide disaster of a Mine Quarter seriously threats the life safety of the resident below，through the geological survey，two more unstable slopes with the widths of 31 m and 30 m respectively were developed in south and north sides of the slip mass.To study the west slope of the neighborhood systematically，MSARMA Analysis and Evaluation System of Stability based on the MSARMA method had been applied to process the quantitative evaluation and sensibility analysis of No.1 unstable slope of quarter neighborhood，which provided scientific bases for reinforcement scheme and monitoring program of west slope of quarter neighborhood.

Key words: Landslide disaster, MSARMA method, Scientific computing, Stability assessment
