Abstract. The article is focused on analyzing the design solutions of wind turbine foundations in the conditions of the Arctic zone. The study considers the requirements for the foundations for wind turbines placed on permafrost bases. Both domestic and world experience in designing foundations for wind turbines has been analyzed, which allowed to systematize proven and perspective design solutions of foundations for harsh conditions. The classification of foundations for arctic wind turbines based on the configuration, structural design and type of permafrost ground is proposed. As a result of the research static and dynamic impacts on the foundations and grounds of arctic wind turbines, methods of their determination are emphasized. The sequence of calculation justification of the foundation of the arctic wind turbine is proposed.
Keywords: foundation, permafrost ground, arctic wind turbine, modeling, static and dynamic impacts, design.

Abstract. The article reports on the main reasons leading to emergency situations in hydraulic structures, examines various calculation methods that allow predicting the thermal state of soils, and reveals the relevance of such calculations. Using the examples of a tailings dam and a drinking reservoir dam, the engineering and geocryological conditions of the placement sites were considered, the initial data was generalized and the engineering and geocryological conditions were schematized, on the basis of which calculated thermophysical models were built with and without taking into account convective heat transfer in a two-dimensional setting. Based on the modeling results, the influence of convective heat exchange on the temperature regime of the dam soil and foundation was assessed.

THE EXPERIENCE IN STUDYING THE INTERACTION OF AN ICE WITH HYDRAULIC STRUCTURES IN AN ICE BASIN

Krylov State Research Centre

Peter the Great St.Petersburg Polytechnic University
Abstract. The study of global ice load is an important aspect of research for the fixed marine structures. The stability on the ground is a critical operating condition for such type of marine structures. These include almost all offshore structures and part of the infrastructure of port facilities. For structures such as protective dams, the problem of determining the global ice load is usually not an issue. It is important here to determine the nature of ice encroachment and possibility of ice getting onto the upper surface of the dam. In addition, it is extremely important to consider the safety of the dam surface, for example, reinforced with riprap, when interacting with ice. Examples of these and other completed studies, as well as the features of their implementation, are highlighted in the paper.
Keywords: hydraulic structures, ice model tank, ice load, limit momentum scenario, model tests

Abstract. The results of experimental and computational hydraulic studies devoted to the study of flow regimes in the downstream and erosion of the Vakhsh River bed during the joint operation of the right-bank water outlets of the Rogun HPP at various stages of construction and operation of the hydroelectric complex are presented. The studies were carried out on a physical model at a scale of 1:60 and on a mathematical model. The flow regimes in the downstream, deformations of the river bed and the backwater of the hydroelectric power station were assessed during the joint operation of outlets. A comparison has been made of the parameters of jet throwing from the flip buckets of outlets when the discharge flows are coupled with the downstream and the flow regime in the Vakhsh River, determined from the data of a physical and mathematical model.
Keywords: spillways, tunnel outlet, HPP powerhouse, water levels, flow velocities, channel de-formations, physical model, mathematical model

ANCHOR SYSTEMS FOR HOLDING FLOATING OBJECTS: PARAMETRIC EQUATION OF A CHAIN LINE WHEN CALCULATING FLEXIBLE LINKS
Vladimir V. Mishchenko
JSC «Lenhydroproject»
Abstract. The software «Anchored Structures» allows you to calculate anchor connections of various configurations, while taking into account their stretching, the presence of masses and buoyancy located on the ties, the rigidity of the tension connection, the possibility of laying part of the connection to the bottom of the water area, which, in turn, may have a slope. The presented method of calculating anchor connections based on the parametric equation of the chain line allows solving similar problems using standard mathematical programs (for example, Mathcad).
Keywords: anchor retention system, chain line, anchor bond reaction
