Abstract :

It is becoming a great challenge for the civil engineers to design suitable foundation for the structures on marine clay. The paper presents an innovative design for construction of foundation on marine clay soils. In this process geofoam, Expanded Polystyrene (EPS) is placed below foundation. Geofoam properties like lightweight, high strength give best option as fill for poor quality of soil. The various combinations of sizes and density of geofoam under footing, for reduction of settlement are studied. A numerical finite element analysis program, PLAXIS, was used to simulate the problem. The decrease in settlement under the footing and the increase in bearing stresses were compared to those without EPS. Load settlement relationship was studied. Results concluded that use of Geofoam (EPS) decreases the settlement and increases the footing load. EPS thickness appeared to be an important factor in improving footing behavior on marine clay, compared with density of geofoam (EPS)
