Rozrakhunok nadzemnoi dilnytsi mahistralnoho truboprovodu na stiikist [Stability calculation for aboveground stations of pipeline]
The mathematical model of stress-strain state aboveground station of pipeline is investigated with taking into consideration interaction aboveground part of pipeline with adjacent to it parts of underground pipeline. The underground parts of pipeline which leaning on the soil are considered as elastic Winkler type basis. Local weakening station of pipeline in connections areas underground part of pipeline with aboveground part are simulated by the introduction elastic joints into a system.
