To summarize the proposed simple modeling method, the retaining wall is taken as a cantilever and the concept of dynamic interaction springs used in evaluating pile response is applied in order to represent the resistance of the backfill soil using springs and dashpots. A comparison of the simple modeling method with the 3D-FEM analysis showed that, despite slight differences in maximum response displacement and hysteresis loop shape, the lateral resistance characteristics corresponded well. This paper also conducted a collision analysis using the simple modeling method, and the results of this analysis also corresponded well with the 3D-FEM analysis results.
