Abstract
This paper base on the actual form and structure of the original bridge piers actual data, according to the exposure collision theory and nonlinear finite element analysis theory, using LS-DYNA software, research the realationship of drift ice strength, modulus of elasticity, thickness factors with affecting convection ice impact force, while the drift ice impact force impact of the bridge was tested and simulated contrast. Simulation results show that the impact force with the flow of ice floe strength, elastic modulus, the increase of the thickness of the ice sheet was an increasing trend.
