| description | The relevance of the study is caused by the need to improve the operational reliability of trunk pipelines laid on permafrost soils. This direction of development of oil and gas transportation and building up the raw material potential is resource-saving, minimizing the amount of operating costs for survey and geomonitoring. Supports of aboveground main pipelines are subjected to loads from the ground due to dangerous cryogenic processes of frost heaving caused by very low temperatures.
The main aim of the research is to determine and propose a support structure for aboveground main pipelines laid on permafrost soils and the possibility of effective use of the sharp edge of the base plate as the aboveground support.
Objects: aboveground main pipeline, permafrost. Soils are characterized by strong heaving and high modulus of deformation.
Methods: modeling of a base plate with frozen soil, assessment and analysis of the fracture stress of frozen rock.
Results. A supporting structure protecting the aboveground main pipeline from the forces of frost heaving is proposed, a base plate with frozen soil is simulated, equivalent stresses of the sharp edge are calculated in the most likely case of cutting expanded clay from the effects of the forces of frost heaving of the soil. |
