THE EFFECTS OF COMPACTION ON RETAINING WALLS

It is widely recognized that compaction of fill behind earth retaining structures can induce lateral earth pressures that vary considerably in magnitude and distribution from those predicted using classical earth pressure theory. This paper presents a simple analytical method which relates induced lateral earth pressures to the effective line loading imposed by compaction plant. Although by no means definitive, the method proposed permits a meaningful assessment of compaction-induced lateral pressures without recourse to complicated mathematical models. Predicted pressures are compared with observed pressures from two case histories, in a third case history the performance of a retaining wall is compared with predictions made using classical theory and the proposed method. A comparison is made between the factors of safety assumed to exist in conventional retaining wall design and those resulting when compaction effects are taken into account. (Author/TRRL)
