The Role of Expanded Polystyrene and Geocell in Enhancing the Behavior of Buried HDPE Pipes under Trench Loading Using Numerical Analyses
Original language description
In recent years, much research has focused on the use of various materials for relieving and strengthening soil, e.g. steel reinforcing ribs, geosynthetics, geocells, waste tires and expanded polystyrene (EPS). EPS is being used more and more in geo-infrastructures, being a super-light material to replace part of the soil and decrease the ground pressure on buried structures. This paper presents an experimental and numerical analysis of the effectiveness of expanded polystyrene and geocell reinforcement for ameliorating the behavior of unpressurized buried pipes exposed to surface loading. A 3-D FEM model of soil, geofoam, geocell, and piping was generated in ABAQUS, and the model was verified by experimental analyses conducted at a laboratory. The results show that reinforcing the soil cover with geocell and geofoam has a substantial impact on decreasing the maximum surface settlement of around 30% and maximum pipe crown displacement by up to 17%. Also, the EPS block density can reduce the maximum pipe crown displacement substantially.
