The book "Program for calculating the temperature regime of massive concrete hydraulic structures during construction and operation" by L. G. Alexeyeva is a unique and valuable publication that will become an indispensable assistant for specialists in the field of hydraulic engineering, architecture and civil engineering. In this work, the author shares his deep knowledge and experience, offering readers a detailed analysis and practical recommendations for calculating the temperature regimes of concrete structures. Temperature fluctuations play a key role in the construction and operation of massive concrete structures. They can significantly affect the strength, durability and stability of structures. Alexev in his book considers how to properly take into account these factors at various stages - from design to completion of construction. It offers readers not only theoretical foundations, but also practical methods of calculation, which makes the book especially valuable for engineers and designers. This work will be of interest to both students studying civil engineering and architecture, and experienced professionals who want to deepen their knowledge in the field of hydraulic structures. The book can also be useful to scientists and researchers dealing with the strength and stability of concrete. It is suitable for those who seek to improve the quality of their projects and want to avoid common errors associated with temperature deformations. The topics raised in the book cover a wide range of issues, including the effect of temperature on the physical and mechanical properties of concrete, methods for monitoring temperature during construction, as well as modern technologies used to control and regulate temperature fluctuations. Alexev emphasizes the importance of an integrated approach to design, which includes not only the calculation of temperatures, but also the consideration of climatic conditions, terrain and other factors affecting the operation of hydraulic structures. The author's style is distinguished by clarity and accessibility of presentation, which makes it easy to assimilate even complex technical aspects. L. G. Alexev is a well-known specialist in his field, and his work has already established itself as a reliable source of information for professionals. In addition to this book, he is also the author of a number of other publications devoted to the design and operation of concrete structures, which confirms his authority and deep understanding of the subject. The book "Program for calculating the temperature regime of massive concrete hydraulic structures during construction and operation" is not just a training manual, but a real find for everyone who wants to improve the quality of their projects and ensure the reliability of concrete structures. It will be an important addition to the library of every engineer, designer and student seeking professional growth and improvement of their skills. If you are looking for information on how to properly take into account temperature regimes in construction, or want to learn more about modern methods of calculation and control, this publication will surely attract your attention. Do not miss the opportunity to see the work of L. G. Alexeyeva and take a step towards new knowledge in the field of hydraulic engineering!
