Original Abstract

At the beginning of the year 2012 the reconstruction of the spillway and the chute proceeded at the Terlicko dam. During the January and February the temperatures decreased below -20 degrees Celsius, moreover the temperatures below -10 degrees Celsius continued for 17 days. During this time the upper degraded concrete layer was removed so the spillway chute slab was only 0.7 m thick. During the February the vertical upward displacements were observed at the chute which was probably attributed to freezing of the foundation joint. Additional geological survey indicated soft and water-bearing layer of a poor quality at the foundation joint between the slab and sub-base slates. In the paper the results of numerical modelling of possible freezing of the concrete slab during the event are discussed. The numerical model of the heat flow demonstrated possibility of freezing of the slab down to the foundation joint which may be the cause of the vertical deformation.
