Abstract

Excessive displacements and/or deformations in engineeringstructures can lead to critical states in stability and to endangeringpublic security. To ensure a continuous and, at the same time, highreliable structure control fibre optic technique is used. In thispaper a description of two sensor applications in hydraulic works isgiven; firstly, an optical waveguide-compatible displacement limitsignaller for monitoring of dam's span joints; secondly, a fibre- optical deformability meter for a watertight core of a rock-fill dam.
