Applications of Geogrid Reinforced Soil Retaining Wall with Wrap-Around Facing in Railway
Abstract The geogrid reinforced soil retaining wall with wrap-around facing on China&s railway line was built and monitored during construction and the first 1.5 years after construction. The reinforcement strains were measured using flexible displacement sensors, and the soil stresses were recorded using vibrating-wire load cells. The maximum vertical foundation pressure along the wall&s reinforcements occurs at the central point of the reinforcement, gradually decreasing toward the front and back ends of the wall. The measured lateral earth pressure within the reinforced soil wall is non-linear along the height, and the value is less than the active lateral earth pressure. The distribution of tensile strain on the geogrid reinforcements within the upper portion of the wall is at a single peak value, but the distribution of tensile strain along the reinforcements within the lower portion of the wall have double-peak values. The potential failure plane within the wall closely follows the active Rankine Earth Pressure Theory. The results presented in this paper are useful in advancing the understanding of the behavior of reinforced soil walls with wrap-around facing.
