Abstract
In cold regions, vertical ice load acts on pile structures due to water level changes, such as tides and swells, as the ice sheet adheres to them. Therefore the vertical ice loads must be fully considered in the design of maritime structures constructed in icy sea areas. When we calculate the ice load, many parameters are needed. One of them, the adfeeze bond strength is an important parameter to calculate the ice load at abfreeze bond failure. And Terashima et al. reported when ice sheet is thick, adferrze bond failure is easy to occur.In this study, we show the characteristic of five testing method for adferrze bond strength between sea ice and various materials, and make the experiment about three testing method for comparison of the influence by changing the testing method. Finally the authors proposed the adfreeze bond strength which is directry used in design.
