Abstract: The objective of the series of tests was to investigate the forces which act on the inclined and vertical structures in the level ice covered area in shallow water, such as the situation in Liaodong Gulf, China. In the series of tests, total 27 ice, sheets wece pushed against a sloped plate with the varied angles from 45° to 90° by using seven ethanol model ice fields wilh the thickness from 22mm to 6) mm. The friction. coefficients of ice and two kind of model surfaces were used. The aim of the tests was to investigate the factors influencing the pill-up and ride-up process, and ice clearing around the structure, In this paper, the design of the structural model, and a summary of the properties of the used model. ice are reviewed. The processes of interactions between ice and structures are described, and the failure modes are discussed. Then, the comparison between the measured total horizontal force and the calculated forces with 2-dimensional and 3-dimensional theory is given. At I. asl, based on the ralio of measured vertical and horizontal forces, the effect of inclination angle and' friction coefficient is analyzed.
