An analytical expression for the seismic passive earth pressure from the c-Φ soil backfills on rigid retaining walls with wall friction and adhesion

Abstract

An analytical expression for the total seismic passive earth pressure from the c-Φ soil backfills on rigid retaining walls subjected to surcharge and seismic loads is derived considering wall friction and adhesion. The derivation also presents an explicit expression for the critical inclination to the horizontal of the failure plane within the backfill. The developed expressions are analyzed for special cases; the resulting expressions are found to be identical to those presented by earlier researchers for both static and seismic passive earth pressure conditions.
