The computer modeling of frost phenomenon effect on piping systems has been conducted with view to analyze the state of the geological medium and to ascertain the origin of all negative situations within gas main pipelines. The developed numerical-analytical algorithm of analysis of strained and deformed state in the system of geological medium-pipeline creates premises for discriminating and forecasting endangered sections within the limits of a pipeline and providing an opportunity to take preventive methods to ensure protected pipeline exploitation. This numerical-analytical algorithm forms the basis of a calculating-analytical modulus that examines a geological-environmental impact on a piping complex and gives away a veritable picture of a change in geological conditions and variation of the strained-deformed state of both trunk pipeline and natural technical-genetic system. Consequently, the quantitative assessment of factors provoking strained and deformed state in the system of geological medium-pipeline in cryolithozone has been given proceeding from accomplished calculations.
