桥梁施工控制中应力监测的温度修正量研究

温度效应将引起桥梁施工控制中应力监测的准确性，本文以某客运专线（60＋100＋60）m预应力混凝土连续箱形梁桥为研究对象，在混凝土内部埋设温度和应力测试元件，采用现场实测的方法研究了温度对结构应力的影响规律，并提出了根据箱梁顶、底板实测温度值进行应力监测实时修正的方法。

Analysis of Temperature Correction on Stress Monitoring During Bridge Construction Control

The temperature effect on stress monitoring during bridge construction should not be neglected. A PC box continuous beam bridge serviced in a passenger dedicated line was employed as an example, which has a computation span of （60＋100＋60） m. Some temperature and stress sensors were buried in the concrete and field measurement were conducted. Based on it, the laws of temperature effect on structural stress were obtained, and a method of real-time temperature correction on stress monitoring was put forward.
