ABSTRACT
ABSTRACT: Large dams are among the most frequently monitored structures. This is understandable, having in mind the consequences of dam failure or equipment malfunction. Over the last decades we have witnessed great progress of measurement techniques and methods, due to the rapid development of materials and equipment. Distributed fiber-optic measurements are among the very promising methods for monitoring dams. The method solves some of the weaknesses of the commonly used measuring methods, e.g. installation and density of the network, which is useful when measuring parameters, such as temperature field changes, formation of cracks, or leaking. In this paper we want to present the results of measurements of the release of temperature measured using fiber optic cables in an early age concrete directly after the placing of mass concrete in the spillway section, the advantages of the presented method for monitoring and controlling the process of hydration, and the release of temperature increment.
