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.], Book Chapter, PUBLISHED  TARA - Full Text

Case writing was based primarily on information from a detailed publicly available article, supplemented with additional input from one author of this article. The case narrative is accompanied by annotated calculations, which follow the general design philosophy of the project. The case focuses on two of the main issues for the geotechnical design of the highway embankments close to the Limerick Tunnel, which are founded on very soft organic fine grained material. First, secondary compression, which is sizeable for this highway project, required surcharging to reduce the rate of long-term settlement. Second, the low undrained shear strength and high compressibility of the foundation material required construction of the embankments in stages, to achieve a degree of consolidation necessary for increased vertical effective stress, increased shear strength and reduced compressibility. This paper includes the case narrative, excerpts from the accompanying calculations, and comments on the instructional decisions involved in the preparation of both.], Conference Paper, PUBLISHED  TARA - Full Text
