Bridge foundations supported by EPS geofoam embankments on soft soil
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...
متن کاملNumerical Analysis of Earthquake Load Mitigation on Rigid Retaining Walls Using EPS Geofoam
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...
متن کاملFEM simulation of full scale and laboratory models test of EPS
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...
متن کاملNumerical Investigation on Performance of Expanded Polystyrene Geofoam Block in Protecting Buried Lifeline Structures
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, ...
