The mitigation of seismic-induced dynamic earth forces by placing a vertical layer of expanded polystyrene (EPS) geofoam buffer between a rigid retaining wall and the backfill soil is a recent geotechnical innovation. In this paper, the influence of an EPS geofoam buffer on the reduction of dynamic wall forces is numerically studied by simulating the results of three reduced-scale models of rig...

EPS geofoam can be used to support highway bridge structures without the aid of deep foundations. The development of this technology is important to accelerate construction on soft compressible soil. EPS geofoam allows for the rapid construction of bridge foundations on such soils without the time and cost involved in installing traditional foundations. Because EPS geofoam is an extremely light...

EPS geofoam has been used for about 40 years in many geotechnical applications in many countries around the world. EPS geofoam possesses properties which are often advantageous in geotechnical construction. These include: an extremely low density, a high strength-to-weight ratio and very small or virtually zero lateral expansion under compressive loading. It has been used for backfilling retain...

Abstract—This paper presents a numerical study for investigating the effectiveness of geocell reinforcement in reducing pressure and settlement over EPS geofoam blocks in road embankments. A 3-D FEM model of soil and geofoam was created in ABAQUS, and geocell was also modeled realistically using membrane elements. The accuracy of the model was tested by comparing its results with previous works...

Abstract The main problem of road construction on saturated soft soils is due to their low bearing capacity and large settlement. One the solutions such problems install piled box culverts-geofoam. In this study, pile culvert-geofoam was modelled as raft foundation. This experimental study conducted by making a prototype file foundation gradually loaded with maximum vertical load 20 kN. Differe...

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...

Abstract—Expanded polystyrene (EPS) geofoam is often used in below ground applications in geotechnical engineering. A most recent configuration system implemented in roadways to protect lifelines such as buried pipes, electrical cables and culvert systems could be consisted of two EPS geofoam blocks, “posts” placed on each side of the structure, an EPS block capping, “beam” put atop two posts, ...

Nowadays, new materials are widely used for improving the bearing capacity of the soils and geosynthetics include the type of these materials which are utilized in this regard. In addition, the geofoam panel type of geosyntethic materials is useful and an alternative for backfill in retaining wall or pavement layers. The present research mainly aimed to investigate sthe effects of geofoam parti...
