Geotextile Reinforced Abutments on Soft Foundation
The objective of this paper is to describe the use of geosynthetic reinforced structures in bridge abutments on soft foundation soils. The characteristics of five geotextile reinforced walls that were constructed on compressible subsoil are presented and discussed. Four of these walls were built on concrete piles with caps, and one was built directly on a sand layer overlaying a soft clay deposit. The designers seem to have aimed for a stiff reinforced mass to distribute stresses to the foundation soil or to minimize differential settlements. Despite rather large vertical or horizontal displacements having been observed, generally the reinforced structures behaved well. Even in one of the cases where a flood caused severe damage to the reinforced mass, the structure was still able to keep the highway in good operational condition. These performances enhance the advantages of using flexible retaining structures in problems where severe differential settlements can occur.
