Located in the interior Anatolian plateau of central Turkey, capital city Ankara, the Augustus Temple has been affected by environmental changes occurring over 2,000 years. “3DEC” software by Itasca and “PLAXIS” software by PLAXIS B.V. were used to analyze the wall at the east side of the Augustus Temple. East side wall was selected, because the condition of the wall was better than the west side wall. Also, the foundation excavation was done close to the east side wall and this gives more accurate information about the wall's overall structure. The analysis was focused on how east wall of the Augustus Temple has still been standing after more than 2,000 years. The foundation structure is selected as the most critical parameter that can affect wall's stability. Eight different 3DEC analyses and nine different PLAXIS analyses were performed in order to show the effect of the foundation and earthquake parameters to the Augustus Temple's wall stability.
