%X In order to  reveal  the deformation law of  a three-level reinforced earth retaining wall in a  V-shaped valley,according to  in-situ test data, we analyzed the changes in  wall panel displacement, settlement of backfill of the wall, settlement of road surface on  high fill, and settlement of the bottom of   culvert beneath the wall in construction period and after completion. Results revealed that the vertical and horizontal displacements of wall panels, and the deformations of the backfill mainly occurred during the construction period, and the values of   displacements and deformations were relatively large. One or two years after the completion, the deformation tended to be stable, but the total cumulative deformation was large, which indicated that the reinforced earth retaining wall could adapt to the large deformation of filling projects, which is an advantage. Moreover, the structure of reinforced high  earth retaining wall beneath high fill in V-shaped valley could meet the challenges posed by  road surface settlement, and the culvert beneath high fill is safe. Besides, since  the   reinforcements of the wall are reinforced concretes, the reinforced earth wall has  some advantages of anchoring board retaining wall and soil nailing wall, which could restrain the deformation of soil mass in the wall, and also serves as a whole to coordinate the deformation of V-shaped valley. Hence the stresses in the fill are redistributed, road surface settlement and deformation are transited smoothly  with no significant  settlement difference and good application effect.
