Three dimensional finite element modelling has been undertaken with the aim of improving current design procedures for the use of soil berms as temporary support during the construction of embedded retaining walls permanently propped at carriageway level. The analyses were based upon 'typical' berm and wall geometries and soil parameters that would be frequently encountered in highway construction schemes. Results from the finite element work, together with factor of safety calculations, have been combined creating sets of 'user-friendly' design aids in the form of charts, aimed at both rationalising and producing economy in the design of soil berms for the temporary support of retaining walls during their construction.
