Component

The effectiveness of an earth berm in providing support to an embedded cantilever retaining wall during temporary works activities is investigated with reference to a particular case study. Finite element analyses were carried out to assess possible movements of the wall during and for some months after excavation. The effect of the assumed lateral stresses acting on the wall prior to excavation was investigated. The results of the finite element analyses are compared with those of a hand calculation based on a modified limiting stress field and a conservative assumption concerning the effectiveness of the berm, and with the wall movements actually measured. The site of the berm was on the new A55 North Wales Coast Road where it passes beneath a causeway on the east side of the Conwy estuary. The soil sections consisted of layers of silty sandy clay, dense gravel, Irish Sea Boulder Clay and glacial lake deposits. (A) For the covering abstract see IRRD 860485.
