Comparison of Russian Norms (Snip) and European Norms (Eurocodes) for Design and Construction Pile Foundations
In this study, the general principles of pile design and construction according to Eurocode 7 and SP 24.13330.2011 regulations are investigated. Although pile foundations are very common in both Russia and Europe, there are many different understanding that starts from soil investigation stage to construction stage. To evaluate their differences, the minimum requirements for soil investigations, suggested approaches for pile foundation design and construction tolerances are comparatively analyzed. Additionally, bearing capacity of pile foundations calculated from suggested approaches are comparatively evaluated and pile load test results for two real cases located in Iraq and Russia comparatively evaluated.
British Standards in compliance with Eurocode 7, requires a more comprehensive site characterization and pile load testing than Russian norms in both preliminary and construction stage. According to the results of analyses, adopting Eurocode 7 and SP 24.13330.2011 codes have similarity in design for ultimate and serviceability limit states. They both adopt partial safety factors to loads and resistances for the ultimate limit state design of the design of pile foundation. However, they visibly differ in terms of the number and content of the design checks, and in terms of the actual values of the partial safety factors. The pile capacities calculated from Russian Norms for both bored and driven is significantly higher than Eurocode 7. Full scale pile loading test results are compared for obtained pile vertical load capacities.
