摘要
以鹤港高速鹤洲水道桥主墩承台为工程依托,考虑在珠海市亚热带气候影响下,通过大体积混凝土温度应力计算,结合现场施工情况,制定出本项目温控标准,并采取了一系列降温措施,最终达到温控预期目标,为类似工程的施工提供了参考。
Based on the main pier cushion cap of Hezhou Waterway Bridge of Hegang expressway,considering the influence of subtropical climate in Zhuhai,through the calculation of temperature stress of mass concrete,combined with the site construction situation,the temperature control standard of the project is formulated,and a series of cooling measures are taken,finally reaching the expected temperature control goal,providing a reference for the construction of similar projects.
