Implementing Eurocode 7 to achieve reliable geotechnical designs in, editor(s)P. Arnold, G.A. Fenton, M.A. Hicks, T. Schweckendiek and B. Simpson , Modern Geotechnical Designs Codes of Practice, Amsterdam, IOS Press, 2013, pp72 - 86, [Trevor Orr]
Notes: [This chapter examines how the different measures to achieve safe and reliable geotechnical designs are implemented in Eurocode 7. These measures include: the use of the concept of geotechnical categories of take account of the complexity of geotechnical designs, procedures for managing the design and execution processes, requirements for the selection of characteristic parameter values, and recommended partial factor values associated with the three Design Approaches. How the consequences and reliability classes, set out in the head Eurocode, EN 1990, are implemented in Eurocode 7 for geotechnical designs is also examined. In additions, the paper presents the results of surveys to investigate how Eurocode 7 is being adopted in the different European countries and the experiences in some of those countries with its implementation.]
