摘　　要：分析了防撞墙及箱梁支座垫石等混凝土结构的特点。在研究了在偏低温自然养护与标准养护条件下混凝土力学性能、抗渗性能和抗冻性能的发展规律,从保证混凝土结构耐久性出发,对冬季低温天气偏薄、偏小的混凝土结构物的施工与养护提出参考意见,对工程建设具有指导意义。The characteristics of concrete structures of collision wall and bearing pad-stones of box girder are analyzed.The concrete mechanical properties,impermeability and freezing-thawing durability in both low-temperature natural curing and standard curing conditions are contrasted.In order to ensure concrete structure durability,the suggestions on construction and curing of thin and small concrete structure constructed in winter are made,which will be of guiding importance for engineering construction.
