EN 1997

In the eurocode series of European standards (EN) related to construction, Eurocode 7: Geotechnical design (abbreviated EN 1997 or, informally, EC 7) describes how to design geotechnical structures, using the limit state design philosophy. It is published in two parts; "General rules" and "Ground investigation and testing". It was approved by the European Committee for Standardization (CEN) on 12 June 2006. Like other Eurocodes, it became mandatory in member states in March 2010.
