结构材质状况耐久性检测及综合评定实例在钢筋混凝土T型梁桥的应用

Application of Structural Endurance Detection and Synthetic Assessment Method to Reinforced concrete T-girder Bridge

以某钢筋混凝土T型梁桥的检测为例,介绍混凝土旧桥表观损伤、强度、钢筋锈蚀电位、氯离子含量、钢筋分布及保护层厚度、混凝土碳化深度、电阻率、内部缺陷和表层损伤等的检测方法与评价指标及结构或构件的耐久性综合评定方法。

Setting an example on certain reinforced concrete T beam bridge,The dissertation instroduces the concrete bridge detect method and evaluating indicator of apparent damage,intensity,rust-eaten potential of concrete bar,content of Cl.,distribution of concrete bar,thickness of covering layer,carburization penetration,electrical resistivity and internal defect.The dissertation also introduces the reseach on synthetic durability evaluation of construction or structural member.
