桥面混凝土裂缝是桥梁施工中的一个通病,裂缝将不同程度地降低桥面整体性和耐久性,影响桥梁的使用寿命,严重者可能导致质量事故的发生。尽管大批工程技术人员和管理人员在这方面作出了坚持不懈的努力,但“裂缝”依旧像一名顽强的杀手,困扰着人类,因而必须高度重视、严加控制。笔者就从事的施工实践对桥面水泥混凝土早期裂缝的原因加以分析,并提出一些防范措施,供施工同仁参考。 Cracks in bridge deck are common problems in bridge construction. Cracks will reduce the integrity and durability of bridge deck to varying degrees and affect the service life of bridges. In severe cases, quality accidents may occur. Although a large number of engineers, technicians and managers have made unremitting efforts in this regard, the “crack” is still like a stubborn killer that plagues human beings. Therefore, it must be given high priority and strictly controlled. The author engaged in the construction practice on the deck of concrete cracks in the early analysis of the reasons and put forward some preventive measures for construction colleagues reference.
