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 assessment of pressures to Eurocode 7, how confident are you that the assessment is sound?
Q4-7. Not used.
Q8. What is the design depth of the water table dw,d(SLS) in the serviceability limit state for the three situations?
Q9. How did you choose the design water level for the SLS?
Q10. Please explain the reasons for your answer to Q9
Q11. What is the design thrust on the wall due to water pressure Pw in the SLS?
Q12. What is the design thrust on the wall due to effective earth pressure P'a in the SLS?
Q13. How did you determine effective earth pressures on the wall for SLS?
Q14. Please explain the reasons for your answer to the previous question (plus any assumptions made)
Q15. What is the design depth of the water table dw for the three design situations in the ULS?
Q16. How did you choose the design water level for the ULS?
Q17. Please explain the reasons for your answer to Q16
Q18. Which country's National Annex did you use to interpret EN 1997-1?
Q19. Which Design Approach did you use for verification of the Ultimate Limit State (ULS)?
Q20. What values of partial factors did you use for this ULS verification?
Q20a. If you used a second combination of partial factors, what values did you use for this second combination?
Q21. What partial factor did you apply to the action arising from characteristic water pressures?
Q22. What is the design thrust on the wall due to water pressure Pw in the ULS?
Q23. What is the design thrust on the wall due to effective earth pressure P'a in the ULS?
Q24. How did you determine effective earth pressures on the wall for ULS?
Q25. Please explain the reasons for your answer to the previous (plus any assumptions made)
Q26. What other assumptions did you need to make to determine earth and water pressures?
Q27. Please specify any other data that you would have liked to have had to determine earth and water pressures
Q28. How conservative do you consider your previous national practice to be for this design example?
Q29. How conservative do you consider Eurocode 7 (with your National Annex)to be for this design example?
Q30. How does your Eurocode 7 'design' compare with your previous national practice?
Q31. Please provide any other relevant information needed to understand your solution to this design exercise
