摘要

The Vuhred gravity dam was built on the Drava River, in Slovenia, in 1956. It was renovated in 2003. Its structural height is 33 m, and the dam crest has a length of 167 m. It is a so-called 'large dam', and for this reason it needs to be monitored on a long-term basis. Long-term monitoring of the Vuhred dam spans nearly 40 years and includes the following types of measurements and inspections: deformation measurements, visual inspections, groundwater measurements, and measurements of external loads on the dam. Automatic measurements of dam monitoring, which started in 2006, permit continuous monitoring of some important parameters, which means that quick decisions can be made in the case that something starts to go wrong, i.e., when the measured values exceed the limit values. The results of continuous measurements, under the influence of external loading, have confirmed the results of previously carried out manual measurements. Analysis of the results of all the measurements (both manual and automatic), as well as the results of inspections, have shown that, under static loading, the Vuhred dam is globally stable and safe. Dam safety is within the presently defined limits, and this is the main goal of dam monitoring - to ensure that the observed dam structure possesses adequate strength and stability.
