The purpose of the work is to create methods, diagnostic models, computational algorithms and technical means for solving problems of diagnostics of urban underground pipeline systems. The content of the work. The work is devoted to solving the problems of developing new methods for qualitative diagnosis of underground pipelines of heat networks that take into account the peculiarities of the distribution of acoustic signals through pipelines. A general methodological approach is provided, based on building a diagnostic model of the pipeline section first, calculating the arrays of correlation functions of information signals, which are then used to form arrays of diagnostic parameters sensitive to the interference of acoustic waves. Further, these parameters are used as control quality parameters when solving a diagnostic problem in the form of a nonlinear programming problem.
