摘要
为了有效判断我国目前使用的混凝土桥梁箱梁的耐久性,对3座预应力混凝土连续箱梁桥进行现场调查。调查的主要内容包括预应力孔道压浆密实程度、普通钢筋的保护层厚度、混凝土碳化深度以及预应力孔道位置等。调查结果可为工程人员判定和研究实际桥梁的耐久性提供参考。
In order to effectively evaluate durability of our country＇s bridges that are used at present, three prestressed concrete continuous box girders are investigated in site. The main investigation includes grouting compactness of prestressed ducts, concrete cover width of box girders , concrete carbonation depth and position of prestressed ducts etc. The survey can be referenced by the engineers to evaluate and research durability of bridges.
