Ice flow produced in the seasonal frozen river in spring will seriously threaten the safety of embankment buildings.It is necessary to carry out research on the influential laws of the drift ice on structures.Taking the bank of Shengli dike in the Songhua River,Tangyuan County as an example,we establish a numerical analysis model of bank protection structure under the action of ice load based on the structural geological terrain using ANSYS/LS-DYNA to carry out a finite-element analysis of the bank protection structure under the ice row’s impact and clarify the variation rules of structural bearing force,so as to provide theoretical reference and technical support for the design and post-maintenance of the bank protection structure in seasonal frozen areas.
