The computer program for slope stability analysis with circular slip surfaces and geotextile reinforcement STABGM may be used to analyze internal and external stability of roadway embankments constructed on permafrost. Internal stability refers to the stability of the embankment slope alone. Thus, the circular slip analyses to be employed are restricted to failure through the toe of the embankment. External stability refers to the stability of the embankment and foundations soil combined. For embankments constructed on soft soil, this is the most likely mechanism of failure. Two computer programs were utilized to analyze the perplexing roadway conditions of the Farmers Loop Road in Fairbanks, Alaska. FEADAM84 A Computer Program for Finite Element Analysis of Dams was initially used to model existing roadway conditions. SSTIPN Soil Structure Interactive Program was then used to model conditions for a reinforced roadway embankment constructed on permafrost.
