Abstract: Retaining walls in partial cut and partial fills are frequently encountered in the construction practice. However, the design of these walls are assumed either completely in the cut or completely in fills so that the construction these walls are often not cost effective. This paper discusses a new approach of using composite structure for the design and construction of partial cut and partial fill retaining walls with the combination of secant pile for the cut portion and reinforced earth wall for the fill. This combination of different retaining wall types do not require new design and construction methodology so that it can be widely applied.
