The narrow-backfill walls are common geotechnical structures that are constructed in hilly terrains for building up the pavements. Rankine’s method or Coulomb’s earth pressure theory over-estimates the lateral earth pressure acting on the narrow backfill walls resulting in an uneconomical design. The paper presents the behavior of the wall retaining a backfill with narrow width under rotation about the bottom mode of wall movement. The finite element approach is adopted to address the present problem. The results obtained from the model are compared with an existing centrifuge model test to validate the model. The earth pressure distribution on the retaining wall for different widths of the backfill is presented. The reduction in the earth pressure coefficient with respect to Coulomb’s coefficient for different widths of the backfill is reported. The failure planes for different widths of the backfill are obtained from the strain contours. These failure planes suggest that as the width of the backfill reduces, the soil mass participating in the failure reduces, resulting in the reduction in lateral earth pressure acting on the wall.
