在桥梁施工中,混凝土裂缝是常见的问题,然而,裂缝的产生对桥梁寿命的影响是巨大的。必须在施工中,全面分析裂缝产生机理,控制施工温度,对于产生的裂缝必须采取积极有效的措施,这样才能确保桥梁质量。针对钢筋混凝土结构中出现的裂缝问题,从设计,荷载,原材料,施工等方面对产生裂缝的各种因素进行分析,并提出防治措施。
Concrete cracks are a common problem in bridge construction. However, the impact of cracks on bridge life is enormous. During construction, a comprehensive analysis of the mechanism of crack generation and control of construction temperature must be taken in order to ensure that the quality of the bridge is maintained. In view of the cracks that occur in reinforced concrete structures, various factors causing cracks are analyzed from the aspects of design, load, raw materials and construction, and control measures are put forward.
