Soil-nailed wall design : incorporating capillary cohesion to assess the temporary excavation stability of “cohesionless” soils

It is well known that soils cannot be excavated vertically without some cohesion being present in the soil mass. Soil-nailed walls require the excavation to proceed in unsupported vertical lifts before the application of a stiff shotcrete-and-mesh facing, and therefore require cohesion.
