Abstract:
Damage of piles under driving in water may be caused by temperture increases or pore water pressure increase or both in combination. Calculations show parasitic stresses up to 10 MPa for certain assumptions. The phenomenon may have implications for other types of concrete structures in water, depending upon loading conditions and material properties.
