摘要：
Forced cyclic lateral displacements took place at the wall by thermal expansion/contraction of RC facing of a 11 m-high U-shape soil retaining wall due to daily and seasonal changes of the temperature, which resulted into large residual lateral displacements toward the active side of the wall due to the increment in the residual earth pressure as well as large settlement in the backfill behind the wall facing. A set of small-scale model tests was performed in the laboratory. It was found that these detrimental effects can be removed by reinforcing the backfill with polymer geogrid layers that are connected to the back face of thin RC facing.
