摘要
溪洛渡大坝LA区置换混凝土浇筑时,在混凝土内部布设了常规点式温度计(电阻式)和分布式光纤,分别监测混凝土内部温度。通过对两种测温方式的监测成果进行比较可知,两种方式的测温成果误差服从正态分布,分布式光纤测温平均精度为1.5℃。
In the course of LA replacement concrete pouring,resistant thermometers and distributed optical fiber were laid in concrete to monitor the internal temperature.By comparing the temperature measurement data,the errors of two measurement methods are normally distributed,and the average accuracy for optical fiber is 1.5 ℃.
