以上海市外环线沉管隧道工程为依托,对其管段混凝土温度等进行监测,把现场测试数据与理论计算进行对比,得出了混凝土温升的规律以及防止裂缝产生的措施。 Based on the project of immersed tunnel in Shanghai Outer Ring Road, the temperature of the concrete in the pipe section was monitored. The field test data were compared with the theoretical calculation, and the law of temperature rise of concrete and the measures to prevent the occurrence of cracks were obtained.
