舞阳河特大桥主墩承台常常为大体积混凝土施工,结构安全、工程造价、施工质量与大体积混凝土的施工技术密切相关。因为水泥混凝土的凝结硬化过程和施工现场环境差异,混凝土往往内外温差较大,容易导致裂缝及其他问题的产生。本文结合某特大桥对高墩连续钢构主墩承台的有关施工技术进行全面研究,通过对各类高墩承台施工技术对比,分析主墩承台施工常见问题及提出避免措施,为桥梁主墩施工确定一个最经济、最行之有效的方法。
Wuyang River Bridge pier pier pier often large-volume concrete construction, structural safety, project cost, construction quality and mass concrete construction technology is closely related. Because of the condensation and hardening process of cement concrete and the differences in the construction site environment, the temperature difference between concrete and concrete often leads to cracks and other problems. In this paper, with a bridge on a high piers continuous steel pier pier mainstay of the construction technology to conduct a comprehensive study of all kinds of high pier pier construction technology comparison, analysis of the main pier pier construction common problems and propose measures to avoid, as a bridge Construction of the main pier to determine one of the most economical and most effective way.
