Seismic behaviour of earth reinforcement walls

The paper presents the experimental results of a test programme performed on the shaking table of Bristol University, UK. Two similar models of reinforced soil retaining walls, one of conventional type and another self-confined, have been investigated. Both models supported the same elastic structure and were submitted to inputs of increasing intensities. The seismic behaviour of the models was comparatively analysed with the aid of cumulative diagrams of settlements, horizontal displacements and response accelerations. The ultimate limit state occurred by tilting of the facing, but the two models reached this state differently. The numerical models revealed the local phenomena that developed in the reinforced soil as well as the large influence of the elastic structure. Both conceptual design and the development of numerical analysis are supported by the results. For the covering abstract see ITRD E125786.
