This study focuses on stability of embankment slope or back slope along the highway in the mountain areas. Those risk slopes were already stabilized in order to increase their stability by several ground improvement technics, for example, soil nail, shortcrete and ground anchor during late 20th century. This studied base on simulate the deterioration rate of ground anchor by considering statistic approach, for example, Weibull distribution and Markov chain for the purpose that to find the optimum maintenance strategy for each type of geological condition such as Rhyorite, Granite, Gabbro and Sedimentary rock. In addition, these studied results were comparing with the observation data from filed test by lift-off test as well as visual inspection of ground anchor head by expert person. Finally, stability of slope also depending on ground water condition from rainfall that high in monsoon season and low in drought season. Therefore, this study also conducted numerical analysis and simulation the stability for long term.
