Lateral Earth Pressure between two Parallel Rigid Retaining Walls [ ]


Parallel retaining walls are usually used for jetties, docks and cutoff walls. The lateral earth pressure is a significant design parameter in retaining structures and in number of foundation engineering problems. Retaining walls require quantitative estimate of the lateral pressure for either design or stability analysis. It is known that the distribution of lateral earth pressure against retaining walls is neither triangular nor linear owing to the effect of arching in the backfill. This paper presents experimental evaluation of the reaction induced by lateral earth pressure from granular soil contained between two parallel rigid retaining walls when the distance between the two walls is narrow.
