Abstract

This paper based on having research conclusion, according to the Coulomb’s earth pressure theory, from the condition of the equilibrium of the force when the slide wedge was in limit equilibrium, thinking about most infaust condition to retaining wall stability during earthquake, a formula was derivated for the calculation of passive earth pressure of cohesive or non-cohesive backfill soils. This formula could be used in the calculation of earth pressure with superimposed load uniformly distributed on any location of ground surface behind retaining wall. Some suggestions were proposed to the calculation of earth pressure in gravity retaining wall design in high frequency earthquake region considering earthquake force.
