Investigation of Seismic Design Methods of Retaining Walls

The purpose of this study is to investigate the seismic design methods of the retaining walls. Seismic behavior of the retaining walls for dynamic loads, seismic design and stability of these structures during the earthquake were studied by studying retaining wall design methods. The overall lateral pressures during earthquake vibrations are the static pressures that occur before the earthquake and the dynamic pressures generated by the earthquake, and the wall response is affected by both pressures. The results of this study show that if there is a possibility of sliding, rotating, or deforming to a sufficient degree to be able to mobilize the active soil pressure, the dynamic wall pressures will be applied via static or semi-static Mononobe -Okabe methods. In case of impermeability of the retaining walls (fixed walls), elastic analysis is also performed, and the most common dynamic analysis methods include the Mononobe -Okabe semi-static method, the Steedman - Zeng method, the Wood method and the Westergaard method, which can be developed.
