30 Principals of Sheet Pile Foundation Sheet piles with vertical load bearing capacity No slab action between bottom slab and sand fill. Accidental loads, Ship Impact, absorbed i sand fill. Forces between bottom slab and sheet piles transferred in shear studs. Approx 3000 shear studs per pier

31 Advantages Principals of Sheet Pile Foundation Use of sheet pile anyway necassary for temporary works Robust design for accidental load capacity. Questions / Problems / Difficulties Requirements for controlls in production phase. Verification of load bearing capacity. Verification of sustainability (corrosion)

32 Verification of load bearing capacity Before production Installation of test sheet piles Evaluation of load bearing capacity with CAP- WAP analysis Use of Dansk Rammeformel Resulted in a criteria for final blow of sheet piles Production sheet piles was installed according to the criteria

33 Controlls during production Controll av sand compaction Installation of inclinometers Measuring of geometrical entities Length Positions in plan Deflection Inclination Fulfilling of criteria for final blow

34 Controlls after production Designers verification of the results from production New independent calculation based on the results from production

35 Design is based on Verification of sustainability Corrosion 120 years life expectancy Maximum allowed corrosion over life-span No corrosion protection of sheet pile

36 Verification of sustainability Corrosion Uncertainty of actual corrosion rate has led to Extra monitoring sheet pile installed A statistic modell for evaluation of allowed corrosion over time has been developed Monitoring sheet pile to be pulled up and investigated over the years to come
