桥梁承台大体积混凝土施工技术

The construction technology of bridge cushion cap mass concrete

近年来,由于大体积高性能混凝土基础已越来越多地应用于大型桥梁工程中,为保证工程质量、减轻或避免温度裂缝,必须进行温度控制和温控监测。如何能总结出一套较为成熟的技术与工艺,是工程技术人员探讨的话题。文章结合工程实例主要就承台大体积混凝土施工工艺、温控措施及温控监测进行了阐述,为今后类似工程起到良好的指导作用。

In recent years, due to the large volume of high -performance concrete foundation has been increasingly applied in large bridge engineering, to ensure the engineering quality, reduce or avoid temperature crack, temperature and temperature control must be monitored. How can a relatively mature technology and process is discussed, and the engineering technicians. The paper combined with engineering examples, the main mass concrete construction technology, the temperature control measures and temperature monitoring are discussed, and gives a good guidance for the similar projects in the future.
