苏通大桥南主塔墩承台为超大体积混凝土,为防止出现温度裂缝,施工中采取了合理分层、双掺技术、内散外蓄、温度应力监测等温度控制措施,有效地控制了混凝土的最高温升和内外温差,施工后的承台质量,达到内实外美,未产生温度裂缝,并根据实际监测数据与温控理论计算进行了对比分析。 In order to prevent the occurrence of temperature cracks, temperature control measures such as rational stratification, double-doped technology, internal bulk storage and temperature stress monitoring are adopted to effectively control the concrete The maximum temperature rise and the temperature difference between inside and outside, the quality of the platform after construction, reaching the inside and outside the United States, did not produce temperature cracks, and based on actual monitoring data and temperature control theory were compared.
