Research Abstract

The seismic risk of landfills was analyzed considering the dynamic interface behaviors of geosynthetic barriers. Firstly the static and dynamic behaviors of geosynthetic interfaces including geomembranes and geotextiles were clarified by tilting tests and sliding block experiments using a shaking table device. Then, sliding failure modes of the whole soil structure under seismic motion were simulated by shaking table model tests. Finally a limit equilibrium stability analysis method was proposed for performance based seismic design.
