Abstract

A series of ice indentation tests have been performed since the winter of 1996 at Lake Notoro in Hokkaido, Japan (JOIA reports: 1996, 1997, 1998 and 1999), as part of the JOIA project. The main factors affecting the total ice load (F) on a structure were investigated using data derived under systematic test conditions, using natural sea ice. The width (W) of the model structure, ice thickness (h), indentation speed (V) and uniaxial compressive strength (σc) are the major factors influencing ice load on a stmcture with a vertical face. The paper determines the dependence of (W/h), (V/h) and (h) on indentation pressure (Pt). It also describes the pressure distribution examined by a 2-dimensional panel sensor that could simultaneously measure pressures at 2112 points for various indentation speeds. From field data, the paper investigates factors explaining the scaling effect, by which the ice load decreases with increasing indentation area.
