摘要:

在对6个矩形、2个T型、2个Π型混凝土梁进行风加速碳化试验的基础上,结合已有工程检测数据,对自然风环境下混凝土桥梁结构的等耐久性设计提出了初步建议。分析结果表明:在实际桥梁耐久性设计中,考虑风加速混凝土碳化具有重要意义和实用价值; 考虑风加速混凝土碳化的桥梁结构等耐久性设计方法较传统耐久性设计方法更加科学合理,理论上避免了梁体各表面耐久性不等的弊病,延长了桥梁结构的使用年限。

Abstract:

Based on carbonization experiments of 6 rectangular,2 T-type and 2 Π-type concrete beams accelerated by wind, combining existing testing data, some primary advices were put forward about equal durability design of concrete bridge structure influenced by wind in natural wind environment. Analytical results show that the concrete carbonization accelerated by wind which has important significance and use value is considered. Concrete carbonization of bridge structure accelerated by wind which is more reasonable than traditional method is considered. The design method can avoid the shortage of durability unequal on beam sections in theory, and extend using time of bridge structure.
