Based on the sliding plane hypothesis of Coulumb's earth pressure theory,a formula was derived for the calculation of passive earth pressure of cohesive or non-cohesive backfill soils with the consideration of the cohesion force on the sliding plane and the adhesive force on the interface of soil and retaining wall. The formula can be degenerated to Coulomb's and Rankine's earth pressure expressions. Results show that the Coulomb's and Rankine's earth pressure theory are the special case of the present solution. A group of graphs about the earth pressure and the slope angle of sliding plane were drawn by the computer program. The limiting value of the earth pressure and the slope angle of sliding plane can be determined from the corresponding graphs. Numerical results showed that the method was feasible,reliable and easily applied in engineering practice.
