Paper Abstract

To acquire the tension of the cable body, a novel measuring method with embedded FBG strain sensor in anchor zone is proposed. This paper describes the design details of the embedded FBG sensor. Based on the analysis of bridge anchor zone, crucial requirements of this sensor are known as package layer structure and the elasticity modulus of the package layer. And the epoxy with micro silicon powder is used as the package layer. Tensile tests are conducted with the tensile testing machine. The result shows that the linearity of sensor is 0.99974, the sensitivity is 2.74pm/N, and the repeatability is excellent. Finally, the sensors are mounted into the cable anchor zone for cable tensile test. The sensor has advantages in linearity and repeatability.
