• Abstract: This paper examines how Eurocode 7 relates to the design of temporary excavation support. It is shown that total stress design and the net available passive resistance method described in Ciria Report 104 can produce inconsistent results, which must be carefully checked for sensitivity to the soil parameter values used. Many temporary excavations are designed using moderately conservative soil parameter values and a limit equilibrium method of analysis with a lumped factor of safety of 1.5. It is concluded that design in accordance with Eurocode 7 produces higher propping forces than design using this approach, but that Eurocode 7 produces propping forces over 60% lower than design in accordance with Ciria Report C580.
