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 30 2014-10-10

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) 31 2014-10-10

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. 32 2014-10-10

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 33 2014-10-10

Controlls after production Designers verification of the results from production New independent calculation based on the results from production 34 2014-10-10

Design is based on Verification of sustainability Corrosion 120 years life expectancy Maximum allowed corrosion over life-span No corrosion protection of sheet pile 35 2014-10-10

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. 36 2014-10-10
