The article provides a method of calculating buried pipelines with structural inclusions on seismic action. Confirmed the relevance of the issue at these high accident areas, in the absence of any specific indication of their calculation in the current regulations. Previously developed technique, because of the need for numerical solutions of systems of differential equations, is not widespread in practice. As part of the rod in terms of the current schematic regulatory approach, analytical expressions for the additional stresses due to the localization of low-frequency oscillations in these areas, and stresses caused by traveling waves (high frequency oscillations). The quantitative evaluation of stress for the most frequently used in practice, pipes and typical soil conditions, as well as a comparison of the data of other researchers.
