The completely revised and extended Recommendations deal with all questions relevant to the planning and dimensioning of geosynthetics-reinforced earth structures. In addition to the demands on materials and analysis principles, the applications of geosynthetics in a range of foundation systems, ground improvement measures, highways engineering projects, in slopes and retaining structures, and in landfill engineering are discussed. The Recommendations have been supplemented by the following sections: – reinforced earth structures over point or linear bearing elements, – foundation systems using geotextile-encased columns, – bridging subsidence, – dynamic actions of geosynthetic-reinforced systems. The remaining sections have been fundamentally revised and updated in line with current standards and codes of practice.

Recommendations for Design and Analysis of Earth Structures using Geosynthetic Reinforcements - EBGEO

With the issue of these recommendations, which have the character of a standard, the «Building Excavations» working group of the German Geotechnics Association (DGGT) aims to provide assistance with the design and structural calculation of excavation support works. The introduction of the Eurocodes for building control purposes made necessary a revision of the previous edition of the recommendations to comply with the requirements of DIN EN 1997-1:2009 together with the national annex DIN 1997-1/NA:2010-12 and the supplementary regulations of DIN 1054:2010-12. All recommendations were thoroughly checked, revised where necessary and adapted to new knowledge. Chapter 10 «Building excavations in water» was substantially revised. Due to the progress of development of measurement instruments and the more stringent requirements, Chapter 14 «Instrumentation for the monitoring and supervision of building excavation support works» was formulated completely anew. The recommendations of the working group «Building Excavations» should be of assistance, – to simplify the design and structural calculation of excavation support works, – to harmonise loading assumptions and calculation procedures, – to ensure the structural stability of excavation support works and their individual elements and – to improve the cost-effectiveness of excavation support works.
