Geosynthetic Strain During Filling Stage of Geosynthetic-Reinforced Pile-Supported (GRPS) Embankments
Abstract This paper discusses designing of geosynthetic tension strain in Geosynthetic-Reinforced Pile-Supported (GRPS) embankments. Traditionally, filling period of the embankment is not considered among design codes, and the arching model is applied to the final state. The paper attempts to adapt existing designing methods to increasing filling height and static compaction load. Adapted designing approaches include codes distinguishing partial-arching and full arching. The variations of stress concentration ratio and tension in the geosynthetic layer are studied with increasing filling height and different overcharge load. Results show that, for certain cases, the maximum geosynthetic strain is acquired while filling, during partial arching with compaction load. This phenomenon is analyzed and validated with two reported cases of field-test data and full-scale experiment, and relative design suggestions are proposed.
