桥梁预应力工程施工难点及技术对策

Construction difficulties and technological countermeasures of bridge prestressed engineering

对桥梁预应力混凝土的优点与不足进行了系统分析,针对桥梁预应力工程的施工难点,从进浆堵管、张拉力控制、滑丝和断丝三个方面入手,总结了相应的技术措施,以提高桥梁预应力工程的整体质量。

The thesis systematically analyzes merits and defects of bridge prestressed concrete. In light of bridge prestressed engineering construc- tion difficulties, starting from three aspects of slurry pipe blocked, tensile force and slippery strands and wire break, it summarizes corresponding technological measures, with a view to improve integral quality of bridge prestressed engineering.
