大体积混凝土硬化过程监测技术研究

Study on Monitoring Technology of Mass Concrete Hardening

应用光纤光栅传感器在试验室及工程现场进行了大体积混凝土的温度监测研究。研究表明,光纤光栅作为温度传感元件的准确性、可靠性及监测的连续性较好,同时,应用光纤B ragg光栅可以捕捉混凝土内部的裂缝出现情况。

By using optical fiber grating sensors in laboratory tests and in-situ project,authors study results indicate that when serving as temperature sensors,optical fiber grating has good accuracy,reliability and monitoring continuity.At the same time,the optical fiber Bragg grating can get the crack emerging situations.
