Abstract

Analysis and design of flexible retaining walls under seismic actions is required in many applications, but is not fully established yet due to the involved complex soil-wall interaction mechanisms. Technology for advanced field measurements and integration with refined numerical analyses represent an attractive option to shade light on this relevant topic of seismic geotechnics. In the present paper, experimental measurements both dynamic and static recorded on a full-scale retaining wall are briefly discussed. Their relevance in view of the development of an effective soil-structure numerical model is pointed out. A multi-level approach to the optimisation of the FE model is discussed, pointing out the potentialities of the integration between field investigations and numerical modelling. The latter is aimed at providing reliable results concerning both the interpretation of the static response and the dynamic behaviour under seismic loads for the development of rational and effective performance based design and assessment procedures.
