Abstract: Within a comprehensive research project aiming at the development of design rules for wooden piles used for coastal engineering purposes, large scale laboratory investigations on vertical ice forces are performed in the Institute for Hydraulic and Coastal Engineering Rostock. Vertical ice forces are effected by an ice cover frozen to the piles. In combination with a rising water level uplift forces on the pile must be expected which may exceed the resistant forces leading to a failure of the coastal structure. In contrast to first assumptions the failure is caused by exceeding ice resistance against bending. In addition the measured vertical ice forces are remarkable higher than calculated by German standard methods (EAU). To dimension the necessary holding forces and to define the necessary ramming depths of (groyne) piles the vertical ice forces on wooden piles are compared to subsoil holding forces measured in field tests on the Baltic coast of Germany.
