Annotation It is noted that the use of modern methods of geophysics in the complex of engineering and geological surveys makes it possible to obtain a more complete understanding of the rocks, without increasing the amount of planned drilling operations. It was revealed that the peculiarities of severe natural and climatic conditions of the permafrost zone, the variability of the cryogenic state of the upper part of the lithosphere and the specific geoecological situation call for the development of new methodological approaches and adaptation, and modern geophysical technologies for solving the variety of engineering-geological problems. It is established that the relevance of this area of work is directly related to the improvement and development of engineering methods of geophysics of cryolithozone, which ultimately stimulates the technological development of engineering surveys as a whole. The problems of increasing the efficiency of studying cryolithozone rocks by modern methods of electrical prospecting are considered. It is shown that the improvement of modern geophysical technologies and the development of new methodological approaches increase the reliability of engineering and geological information in solving actual geocryological problems without increasing and, in some cases, reducing economic costs for the production of engineering-geocryological surveys. It is concluded that a promising direction for further research is to optimize the integration of geophysical methods for diagnosing the development of cryogenic and physico-geological processes in the host rocks of the bases of engineering structures under construction and operation
