Eurocode 7 - geotechnical design

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?

Q4. What correlations did you use to derive soil parameter values (if used) for the ULS verification? If more than one, please list others below.

Q4a. Any other correlations? (please give same info as above)

Q5. What assumptions did you make in choosing these correlations?

Q6. How did you account for any variation in parameters with depth?

Q7. Please explain the reasons for your answer to Q6

Q8. What is the characteristic value of q_{c} at these depths?

Q9. How did you assess these values?

Q10. (If determined) What is the characteristic value of unit shaft resistance q_{s} at these depths?

Q11. (If determined) What is the characteristic value of unit base resistance q_{b} at these depths?

Q12. Which calculation model did you use to determine shaft and base resistance?

Q13. Which country's National Annex did you use to interpret EN 1997-1?

Q14. Which Design Approach did you use for verification of the Ultimate Limit State (ULS)?

Q15. What values of partial factors did you use for this ULS verification?

Q15a. If you used a second combination of partial factors, what values did you use for this second combination?

Q16. What correlation factors (if any) did you use for this verification?

Q17. What model factor (if any) did you use for this verification?

Q18. What length does the pile need to avoid an ultimate limit state?

Q19. What is the design compressive force that the pile must be designed for according to Eurocode 2?

Q20. (If determined) What is the settlement of the pile in the serviceability limit state?

Q21. What other assumptions did you need to make to complete your design?

Q22. Please specify any other data that you would have liked to have had to design this type of foundation

Q23. How conservative do you consider your previous national practice to be for this design example?

Q24. How conservative do you consider Eurocode 7 (with your National Annex) to be for this example?

Q25. How does your Eurocode 7 design compare with your previous national practice?

Q26. Please provide any other relevant information needed to understand your solution to this design exercise
