Abstract Based on the sliding plane hypothesis of Coulomb earth pressure theory，diagonal slice method is used to deduce the formula of active and passive earth pressures，application position of resultant force and formula of earth pressure which considers the cohesion on sliding plane，the adhesive force on interface of soil and retaining wall，the uniformly distributed load，the critical rupture angle of explicit solution are also deduced. The formula effectively proves the Coulomb theory which assumes the earth pressure behind retaining wall is in linear distribution，besides the prevailing classical Rankine and Coulomb earth pressure formulas are two special examples of the formula that are simplified under the condition of relevant assumptions，which is an important supplement for the application of this method.

Key words： soil mechanics retaining wall earth pressure sliding plane Coulomb theory diagonal slice method linear distribution
