The observational method in geotechnical design

As in accordance with Eurocode 7 Part 1, the hen prediction of geotechnical behavior is difficult, so it may be appropriate to apply the approach known as the “observational method,” in which the design is reviewed during construction. This method is applied by following this procedure: limits of acceptability of the values of certain quantities…

DReW Seismic: Displacement of Retaining Walls due to Earthquakes

Stability analysis of embedded cantilever retaining walls in seismic area is generally carried out by calculating a factor of safety against a possible mechanism of collapse. However, a more rational approach consists in assessing the performance of the structure in terms of accumulated permanent displacement (Fig. 1). Indeed, this approach is required by many national…
