The article has summarized findings of the research into the stress-strained state of the concrete dam. Within the framework of this project, the co-authors have analyzed particular features accompanying field data processing, if the concrete dam serves as the data source. The co-authors have derived average linear expansion coefficients for frozen concrete samples originating from varied dam zones. The findings of numerical studies are provided with the account for the variable value of the linear expansion coefficient of the concrete exposed to negative temperatures. Specialized contact methods in finite elements simulations were employed to simulate the casting joints, with the monolith height being equal to 1.5 m, to take account of the non-linear shear strain of joints and their opening. The analysis performed by the co-authors is based on the combinations of loads and other exposures typical for January as the coldest month of an average year. Casting joints were only simulated in the bottom of the finite element dam model, while no joints were simulated for the dam top. The findings have proven, that the 1.53-fold rise in the value of α accompanying concrete freezing, influences the strain state of the dam at Bogouchanskaya hydropower plant. However no effect was produced by the change in the α value onto the strain state of the dam face. Besides, the rock-to-concrete contact depth and width increased. Although, given the small value of the aforementioned increase (decimal points of a millimeter), it will produce no effect on the filtration underway within the bedrock base of the dam. Changes in the value of the linear expansion coefficient of concrete must be taken into account when physico-mechanical characteristics of concrete are identified for the purpose of the finite element analysis.
