DAMAGE AND NON-DAMAGE SIMULATION OF A RESIDENTIAL FILL SLOPE, NANKODAI 6 CHOME, IZUMI WARD, SENDAI CITY, DURING THE 2005 OFF MIYAGI PREFECTURE EARTHQUAKE AND THE 2011 OFF THE PACIFIC COAST OF TOHOKU EARTHQUAKE

Abstract

 Evaluation of residual displacement was conducted in order to simulate process of damage and non-damage to a residential fill slope, Nankodai 6 chome, Izumi Ward, Sendai City, Miyagi Prefecture, during the 2005 off Miyagi Prefecture Earthquake and the 2011 off the Pacific coast of Tohoku Earthquake. First, analyses based on Newmark's Sliding Block Method were carried out using ground motions of the 2005 main shock and 2011 main shock at the site estimated from temporary earthquake observation records. Analyses based on dyamic FEM calculation were then conducted considering the estimated ground motions. The result of the analyses due to the 2005 main shock and the 2011 main shock coincides with the actual damage and non-damage to the residential fill slope of interest.
