摘　　要：公路桥梁冬季施工中,混凝土的养护至关重要。低温环境下,混凝土的水化反应减缓,影响强度增长和耐久性。为解决这一问题,采取了合理的保温养护措施,如覆盖保温材料、加热保温或使用抗冻剂等方法,以确保混凝土在冬季施工中的强度和耐久性不受影响。通过改进现有养护措施,进一步提升了混凝土的抗冻性能和施工质量,减少了裂缝和结构早期损伤的风险,确保了公路桥梁的安全性与耐久性。In winter construction of highway bridges,the maintenance of concrete is crucial.Under low temperature conditions,the hydration reaction of concrete slows down,affecting strength growth and durability.To solve this problem,reasonable insulation and curing measures have been taken,such as covering insulation materials,heating insulation,or using antifreeze agents,to ensure that the strength and durability of concrete during winter construction are not affected.By improving existing maintenance measures,the frost resistance and construction quality of concrete have been further enhanced,reducing the risk of cracks and early structural damage,ensuring the safety and durability of highway bridges.
