摘要
混凝土桥梁上的裂缝问题是一个复杂而常见的问题。分析了混凝土早期裂缝的特征及开裂机理 ,对目前应用广泛的大体积混凝土、高强混凝土、泵送混凝土的裂缝防治措施提出了可操作性的方法。
The cracking in concrete bridges is a complex but common problem. In this paper, the characteristics and the mechanism of cracking in early age of concrete are analysed. The effective and operative methods of preventing and curing the cracks in massive concrete, high strength concrete and pumping concrete are presented.
