摘要
在公路桥梁工程中,混凝土梁易出现裂缝、露筋、表面缺陷等病害,影响工程施工质量及公路桥梁的通行安全。如何提升公路桥梁的混凝土梁施工质量成为亟待解决的关键问题。预应力工艺具有提高构件强度、减少振动和弹性变形等优点,有利于降低混凝土梁质量病害的发生率。基于此,文章针对公路桥梁预制预应力混凝土梁架设技术展开研究,旨在提升公路桥梁工程的稳定性和可靠性,保证公路桥梁交付使用后的过往通行车辆安全。
In highway bridge engineering,concrete beams are prone to cracks,rebar exposure,surface defects and other diseases,which affect the construction quality and the traffi c safety of highway bridges.How to improve the construction quality of concrete beams of highway bridges has become a key problem to be solved urgently.Prestress technology has the advantages of improving the strength of components,reducing vibration and elastic deformation,which is conducive to reducing the incidence of quality diseases of concrete beams.Based on this,this paper studies the erection technology of precast prestressed concrete beams of highway bridges,aiming at improving the stability and reliability of highway bridge engineering and ensuring the safety of passing vehicles after the highway bridge is delivered for use.
