Eurocode 7 - geotechnical design

ETC10 Questionnaire 2.5


Q1. Please provide your contact details in case we need to clarify your submission. (These details will be kept strictly confidential.)

Q2. How many structures of this kind have you previously designed?

Q3. Having completed your design to Eurocode 7, how confident are you that the design is sound?

Ultimate limit state

Q4. Which calculation model did you use to determine the maximum height of the embankment?

Q5. If you used a slip circle method, which variant of this method did you use?

Q6. Which parameters did you use for the ULS design of the embankment?

Q7. What correlations did you use to derive soil parameter values (if used) for the ULS verification? If more than one, please list others below.

Q7a. Any other correlations? (please give same info as above)

Q8. What assumptions did you make in choosing these correlations?

Q9. How did you account for the location of boreholes/vane profiles relative to the embankment?

Q10. Please explain the reasons for your answer to Q9

Q11. How did you account for any variation in parameters with depth?

Q12. Please explain the reasons for your answer to Q11

Q13. What is the characteristic value of cu at these depths?

Q14. How did you assess these values?

Q15. Which country's National Annex did you use to interpret EN 1997-1?

Q16. Which Design Approach did you use for verification of the Ultimate Limit State (ULS)?

Q17. What values of partial factors did you use for this ULS verification?

Q17a. If you used a second combination of partial factors, what values did you use for this second combination?

Q18. What is the embankment's maximum height to avoid an ultimate limit state?

Concluding questions

Q19. What other assumptions did you need to make to complete your design?

Q20. Please specify any other data that you would have liked to have had to design this type of foundation

Q21. How conservative do you consider your previous national practice to be for this design example?

Q22. How conservative do you consider Eurocode 7  (with your National Annex) to be for this example?

Q23. How does your Eurocode 7 design compare with your previous national practice?

Q24. Please provide any other relevant information needed to understand your solution to this design exercise
