Abstract
This paper has described the role and contribution of P.I. Melnikov, Academician of the USSR Academy of Sciences; N.A. Tsytovich, Corresponding Member of the USSR Academy of Sciences; N.I. Saltykov, Professor, and V.F. Zhukov, Candidate of Technical Sciences, to construction of the Yakutsk Combined Heat and Power Plant. These outstanding figures known for their pioneering researches in different fields of permafrost science and engineering were actively and directly involved in the construction project, including the planning and design, foundation analysis, site investigation, foundation construction, and post-construction monitoring. The foundation condition at the plant site, the causes for talik development and the dynamics of talik distribution during the period of authors’ observations have been discussed. The reasons of the quite stable state of all the plant’s facilities despite the widespread talik occurrence have been adduced.
