• Sommario/riassunto: The aim of these recommendations is to harmonize and further develop the methods, according to which excavations are prepared, calculated and carried out. Since 1980, these have been drawn up by the working group ""Excavations"" at the German Geotechnical Society (Deutsche Gesellschaft f?r Geotechnik DGGT) and are similar to a set of standards.They help to simplify analysis of excavation enclosures, to unify load approaches and analysis procedures, to guarantee the stability and serviceability of the excavation structure and its individual components, and to find out an economic design of
