摘　　要：为了解后张法预应力混凝土连续箱梁孔道压浆问题,以3座后张法预应力混凝土连续箱梁为工程背景,采用现场调查方法对箱梁后张法预应力孔道的压浆问题进行了调查研究。调查结果表明,3座桥梁的孔道压浆密实程度均较差,其中梁体纵向、横向预应力孔道中无压浆的截面分别占调查总数的14.5%和47.58%。According to three post prestressed concrete continuous box girders, this paper investigates the duct grouting compactness by field inspection.It is concluded that the duct grouting compactness of three bridges are poor, in which the sections without grouting in transverse and longitudinal ducts are 14.5% and 47.58% respectively.
