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