摘　　要：在高速公路桥梁施工过程中,若施工管理不当,常常会导致桥梁出现混凝土裂缝等质量问题,这些问题会在桥梁运营阶段显现出来。文章以某高速公路大桥箱梁底板裂缝治理为例,详细探讨了预应力钢筋混凝土现浇连续梁桥箱梁底板裂缝的检测方法与工具,以及裂缝加固技术。通过对该桥梁箱梁底板环向裂缝的具体加固处理技术的描述,结合施工过程中的人员、设备、方法等因素,分析了裂缝产生的原因,旨在为类似桥梁缺陷治理提供参考经验。In the process of highway bridge construction,if the construction management is improper,it will often lead to quality problems such as concrete cracks in the bridge,especially in the bridge operation stage.Taking the crack treatment of the box girder floor of a highway bridge as an example,this paper discusses in detail the detection methods and tools of the crack in the box girder floor of the prestressed reinforced concrete cast-in-place continuous beam bridge,as well as the crack reinforcement technology.Through the description of the specific reinforcement treatment technology for the circumferential cracks in the bottom plate of the box girder of the bridge,combined with the factors such as personnel,equipment and methods in the construction process,the causes of the cracks are analyzed,in order to provide reference experience for the treatment of similar bridge defects.
