摘要
光纤传感器在混凝土结构深层裂缝监测方面具有巨大的工程应用价值。本文详细介绍了所研制开发的混凝土裂缝光纤传感器的原理和结构设计。从三点弯曲混凝土梁的加载试验结果看，传感器能很好地感知裂缝的发生和发展，并且在一定的裂缝开度范围内不断裂，从而能适应工程应用的要求。
Fiber optic sensor has potential usage in the inherent crack detection of concrete structures. This paper describes two specially shaped fiber optic sensor designs that were embedded in two 1 meter long reinforced concrete beam. Feasibility and sensitivity of these sensors were conducted on the beams that were loaded to failure. Incipience and propagation of concrete cracks were monitored by using an optical time domain reflectometry(OTDR) and a light intensity meter respectively.
