In regions prone to frequent snow disasters, the operational safety and traffic capacity of bridges are significantly affected by low-temperature ice conditions. Expansion joints often fail due to ice blockage, frost heave, and wear, leading to structural damage and increased traffic accident risks. To address this issue, this study proposes an integrated design method for ice resistance and snow removal in bridge expansion devices. By analyzing the stress characteristics and heat conduction patterns of expansion joints under snowy conditions, combined with high-efficiency de-icing materials, low-temperature anti-freezing structures, and active heating systems, the design achieves synchronized collaboration between ice resistance and snow removal. This approach not only enhances the reliability and durability of expansion joints in extreme climates but also reduces maintenance frequency and operational costs, providing effective technical support for bridge safety in cold regions.
