Application of geodetic methods for monitoring of stresses of penstock on Tereblya-Rikska hydropower station

The long-term dependences for the changes of deformations and stresses in penstock based on the results of many-year investigations are established. Such investigations were held on the spatial geodetic network on the Tereblya-Rikska hydropower station (HPS). The investigations of the short-term stresses and deformations of the penstock with the use of electronic tachеometer Leica TPS 1201 has been undertaken. Direct correlations between the changes of the length of all baulks and the changes of water level in the storage reservoir are determined
