Problems during filling of the reservoir under frozen rock bed conditions and rock-fill dam body are examined. Thawing of the dam bed and body resulted in an incline in the direction of the upper pool, which in turn caused local opening of the joint between the concrete dam and the asphalt-concrete water wall, which is the water-impermeable core of the dam. © 2016 Springer Science+Business Media New York

Problems that can be resolved with use of ground laser scanning are listed. Aproposed procedure for a control survey with use of the method of laser scanning is described in detail. Advantages of laser scanning for updating of control documentation are noted. Basic steps in studies related to the control survey are described. Procedures for determination and analysis of deviations in actual geometry of an entity obtained as a result of laser scanning from the design are cited. © 2014 Springer Science + Business Media New York.

Characteristics of the stress-strain state and seasonal temperature openings of joints on the downstream face of a concrete dam are analyzed for severe climatic conditions. The width of the joint opening is evaluated as a function of the amount of reinforcement and the spacing between joints. Characteristics of the reinforcement of the downstream face of the dam are examined as a function of its functional purpose: the downstream face of the dead-end section, stepped spillway face, and the locations of the abutments of the reinforced-concrete structures. A reinforcement scheme is proposed for the stepped spillway face to minimize temperature-induced stresses owing to freedom of the deformation of the concrete between construction joints. © 2011 Springer Science + Business Media, Inc.

The behavior of a dam during initial filling of its impounded reservoir, which can be characterized not only by the ascent of the water level, but also by warming of the bed of the dam and change in its physico-mechanical properties during filling of the reservoir as a result of its contact with the water, is analyzed. It is demonstrated in this period that it not so much the hydrostatic pressure of the water as the change in the temperature regime in the near-surface zone of the bed that has a major determining effect on deformation of the near-contact zone of the bed. © 2015 Springer Science+Business Media New York.

The pattern of deformations of the Sayano-Shushenskaya arch-gravity dam with its reservoir filled and at a stagnant volume was examined. investigations revealed that a distinguishing characteristic of arch and arch-gravity dams was the three-dimensional character of their deformations, which was caused by a combination of cantilever and arch effects. The sequence employed to calculate the angles of incline of the horizontal sections of the dam to the horizontals involved an increment of horizontal displacement dx of the dam, which occurred for each height increment dy of the dam. The angles of incline of the horizontal sections of the dam permitting identification of the interrelation between the arch and cantilever deformations, represented an extremely important diagnostic parameter in addition to radial, tangential, and vertical displacements that made it possible to ascertain this character.
