Abstract

Plans have been made to re-organize Eurocode 7 to make it more consistent with other Eurocodes, easier to understand, and more comprehensive in its technical coverage. The current Eurocode 7 was published in two parts, Part 1 (EN 1997-1:2004) covering General rules and Part 2 (EN 1997-2:2007) Ground investigation and testing. To allow better coverage of existing topics and space for new ones, the next Eurocode 7 will be divided into three parts: with Part 3 concentrating on Geotechnical Constructions, such as slopes, spread foundations, pile foundations, retaining structures, anchors, ground improvement, and reinforced ground structures. Parts 1 and 2 will be made easier to use and the structure of Part 1 revised to bring it more into line with the other Eurocodes. One aspect that makes the present Eurocode 7 difficult to understand is the provision of three different Design Approaches, each with its own set of partial factors and ‘special’ cases. Each country can adopt any Design Approach within its borders and many have additionally chosen different partial factors from the recommended values given in EN 1997-1. To improve the harmonization of geotechnical design practice across Europe, the next generation of Eurocode 7 will present a simpler, yet more comprehensive system of partial factors, based on material factor and resistance factor approaches. The paper gives details of the current proposal and the reasons behind it.
