Seismic Effects on the Design of Geosynthetic-Reinforced Earth Retaining Structures

摘要

For the purposes of this paper, the study will be limited to developing a design method for earth retaining structures that have been reinforced with geosynthetics and are subjected to cyclic motion such as that caused by earthquakes. It will examine some case studies of the performance of geosynthetic reinforced earth retaining structures (GSRW) and review some time tested concepts dealing with both geosynthetics and seismic earth pressures. Finally, this paper will mesh the various concepts together to form a step-by- step procedure for designing one type of earth retaining structure and compare the results to an equivalent concrete cantilever retaining wall.
