Abstract:A method was proposed to calculate the earth pressure from a cohesionless backfill with a high aspect ratio (ratio of height to width of retaining wall). An exponential equation of slip surface was proposed first. e proposed nonlinear slip surface equation can be obtained once the width and height of the backfill as well as the internal friction angle of the backfill were given. e failure surface from the proposed formula agreed well with the experimental slip surface. en, the earth pressure was calculated usi… Show more
