Two main aspects of the research work are as follows:(1) The paper introduces the experimental ice forces on semi-circular breakwaters which is made by State Key Laboratory of Coastal and Offshore Engineering of Dalian University of Technology and calculate the ice value for different radius semi-circular component, based on which it speculates on that horizontal ice value and water level accord with biquadratic polynomial function, meanwhile, the paper analyses incidence of ice heap to horizontal ice value of semi-circular component.
