Abstract Expanded polystyrene (EPS) geofoam is one of the lightweight materials used in civil engineering applications. Present study deals with application retaining wall as a backfill. In this study, two-dimensional finite element software to simulate geofoam. A 6m height considered. Lateral pressures and surface settlements are examined for various orientations Orientations include upper tri...

An effort is made to evaluate the formulation of seismic active earth pressure behind a nonvertical retaining wall supporting c-Ф backfill. The formulation is prepared to get a single critical wedge surface for simultaneous action of weight, surcharge, cohesion and adhesion. The success of any retaining structure involves the awareness of seismic active earth pressure. The effect of various par...

Abstract A comparative analysis of the solutions for seismic impact on a flexible retaining wall designed to strengthen construction excavation multi-storey building in Sofia has been performed. For this purpose, following FEM calculation models interaction with surrounding soil body were compiled: (1) 1D beam-column-spring model wall, including spring support its embedded length and pseudostat...
