Influence of Compaction Moisture Content on Wetting-Induced Settlement of Embankments
Abstract This paper presents a numerical investigation on the wetting-induced settlement of embankments using a finite difference program. The unsaturated compacted fill was simulated using the Barcelona Basic Model. A field unsaturated embankment subjected to full saturation was simulated as the worst case scenario for embankment design. Simulation results indicate that the embankment fill undergoes settlement as a result of wetting, which could lead to differential settlement between the embankment approach and bridge abutment, and cause damage to the approach slab. The influence of compaction moisture content on the wetting-induced settlement of embankments was also investigated. Results indicate that even though embankments with higher compaction moisture content could result in initial larger settlement under self-weight compression, the potential for subsequent wetting-induced settlement could be significantly reduced.
