摘要：In the seas and rivers in high-latitude regions,the broken ice floes can generate obvious ice load on offshore platform piles and bridge piers,and even cause damage of the vertical piles.Based on the discrete distribution characteristics of ice floes under natural conditions,the Voronoi cutting algorithm was used to construct the initial state of randomly-distributed broken ice floes with irregular geometric shapes.The discrete element method was adopted to simulate the drifting process of ice floes and the interaction between ice floes and vertical piles.The ice floe model with certain thickness,size,shape and other physical parameters was constructed with bonded spheres with consideration to their failure effect.The vertical piles were simplified as rigid structures.A numerical simulation was conducted to determine the ice load on the pile group under the impact of ice floes,and analyze the effects of ice size,ice velocity and ice thickness on the ice load of pile structures.
