In order to explore the contact safety problems of broken iced ultra-high voltage wires on the construction of shed tunnels, a project design sketch is first established based on actual engineering data and the research technical route is determined. Secondly, the iced wires, shed tunnels, and their contact parts are regarded as the research objects, and the APDL modeling method is used to establish a finite element analysis model. The SOLID185 element is utilized to establish the finite element analysis model of the contacted shed tunnel structure, and the BEAM189 element is applied to establish the ANSYS models of six iced lines. Arrange contact element CONTA175 on the iced wire and target element TARGE169 on the foam concrete roof of the shed tunnel which will be contacted by wires, and set the contact pair properties according to the actual working conditions. Contact between the wire and the shed tunnel is performed. Finally, results are obtained from different conditions and they are analyzed, which is beneficial to determine the dangerous contact area on the roof of the shed tunnel.
