Estimation of the Active Earth Pressure with Inclined Cohesive Backfills: the Effect of Intermediate Principal Stress is Considered

摘要

Estimating active earth pressure accurately is very important when designing retaining wall. Based on theunified strength theory and plane strain assumption, an analytical solution has been developed to determine theactive lateral earth pressure distribution on a retaining structure with the inclined cohesive backfill considering the effectof the intermediate principal stress. The solution derived encompasses both Bell’s equation (for cohesive or cohesionlessbackfill with a horizontal ground surface) and Rankine’s solution (for cohesionless backfill with an inclined groundsurface).
