Backfill & Surcharge • The material retained or supported by a retaining wall is called backfill. • Backfill may have its top surface horizontal or inclined. • The position of the backfill lying above the horizontal plane at the elevation of top of wall is called surcharge & its inclination to the horizontal is called as Surcharge angle. 4
