沿海混凝土桥墩墩身早期裂缝分析及控制措施

Early Crack Analysis and Control Measures of Pier Body of Concrete Bridge in Coastal Areas

通过对某沿海特大桥混凝土桥墩墩身早期裂缝的分析,查找了材料、施工、设计等方面的原因,并采取一系列措施控制了裂缝的进一步发生与发展,为夏季高温条件下大体积混凝土实体桥墩的施工与裂缝控制提出了成熟可靠的施工方法。

The reasons for crack were studied from aspects of material, construction and de sign by analyzing the early crack of pier body of a large concrete bridge in coa stal area. A series of measures was taken to control the crack. Reliable methods on construction and crack control of massive concrete pier were put forward und er high temperature in summer.
