...S. S. AbdelSalam; S. A. Azzam Expanded polystyrene geofoam has long been used as a compressible lightweight alternative for soil backfills to reduce lateral pressure behind retaining walls. Uncertainty in material properties and lack of design parameters are the main constraints to using local...

...E.C.G. Santos; E.M. Palmeira; R.J. Bathurst ABSTRACT: Geosynthetic reinforced soil walls are now an accepted technology for the solution of earth-retaining problems due to cost savings, easy and quick construction, and associated environmental benefits. Additional savings and reduction...

...R. J. Bathurst; A. Nernheim; D. L. Walters; T. M. Allen; P. Burgess; D. D. Saunders The paper describes measurements taken from a series of four full-scale modular block walls that were constructed with reinforcement layers having different stiffness. The walls were 3.6 m high and were reinforced...

... to determine the factor of safety for geosynthetic reinforced embankments and retaining walls under earthquake loading. The involvement of the author in developing an empirical procedure to estimate displacements under seismic loading is described. Instrumented wall model tests with light-weight block wall...

...Romero C. Gomes; Ennio M. Palmeira; Daniela Lanz This paper presents the results of tests with reinforced model walls submitted to different loading conditions. Different types of reinforcement materials and layouts were employed. Stress and displacement measurements were taken during the tests...
