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

摘要

Estimating passive 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 the passivelateral earth pressure distribution on a retaining structure when the backfill is cohesive and inclined 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).
