自锚式悬索桥端横梁大体积混凝土温度控制技术研究

Control Technology for Mass Concrete of End Cross Beam of Self-Anchored Suspension Bridge

结合自锚式悬索桥端横梁进行大体积混凝土的温度监测,结果表明,采用铂热电阻测温技术测量大体积混凝土的内部温度是可行的,大体积混凝土的升温过程快,升温幅度明显高于降温幅度,必须根据施工环境特点采取必要的降温和保温措施。

The temperature of mass concrete is monitored combined with the end cross beam of self-anchored suspension bridge.The result shows that it is feasible using platinum thermistor thermometric technology to measure the inner temperature of mass concrete.The heating process of mass concrete is fast,and the increasing extent of temperature is obviously higher than the decreasing extent,so it is necessary to take cooling and in-sulation measures according to the characteristics of construction environment.
