ABSTRACT

Commonly used anchor monitoring systems are mainly based on the use of anchor force meters. However, experience shows that the reliability of the display of force meters lowers over time. Other measurement and test methods like for example fiber bragg grating method require a comparison with an unloaded optical fiber and give only selective information about the bearing behavior. Morover the obtained information has to be interpreted. In the following article, first measuring results of an anchor monitoring system based on measurements with optical fiber are presented. The new monitoring system is based on the Rayleigh technology and was used to test the load bearing behavior of the anchor grout body as well as for the evaluation of the grout body condition in concrete-damaging groundwater.
