Abstract: Systematic tests were carried out to clarify the effects of push-out speed, stress rate, ice thickness, pile diameter, material of pile and ice temperature on the adhesion strength of sea ice to piles by means of push-out test. Steel piles and concrete piles with diameters 3.15,5. 0,10.0 and 15.0 cm were used in ice thickness from 1.0 to 13.0 cm at a moderately high ice temperature ranging from -1.5°C to -4.3°C. Adhesion strength to piles was observed to have a peak value with changes of push-out speed and stress rate. Adhesion strength increased with increasing ice thickness and roughness of pile surface and also increased with decreasing pile diameter and ice temperature.
