Research on Percussive Force of River Ice and Bridge

On the base of experiments, the dynamic of river ice sheet interacting with Huma Bridge is performed with finite element software LS-DYNA. The peak ice force and the peak lateral displacements of top piers in numerical results are consistent with the onsite experiments. Using this model, the effect of ice velocity on ice loads and lateral displacement is analyzed. The results show that the proposed method for dynamic analysis of ice and bridge structure based on experiment is feasible, providing a valuable reference for analyzing the influence factors of ice load and the calculation method of ice load during the design of bridge in cold regions, establishing the solid foundations of the action mechanism of river ice and bridge structure.
