description: The subject of the graduate qualification work is âAnalysis of the stress-strain state of pipelines in permafrost conditionsâ. This work is devoted to the numerical study of the stress-strain state of pipelines in frozen soils; determining the state due to the subsidence, as well as the possible heaving of the soil. Goals that were solved during the research: 1. Determination of the stress-strain state of the pipeline during subsidence. 2. Investigation of the dependence of the pipeline deflection on the size of the area of subsidence of the soil, the pressure of the pumped gas, physical and mechanical parameters of the soil. 3. Investigation of the conditions for the occurrence of soil heaving. 4. Estimation of Mises-equivalent stresses in the pipeline during subsidence. 5. Assessment of vertical movement of the pipeline during subsidence. The analysis was carried out by the method of finite element modeling using the software âANSYSâ. Based on the research, the following conclusions were made: the maximum stresses in the model do not exceed the critical ones, the forces of frost heaving do not exceed the weight of the pipeline section, and the heaving process will not occur. The pipeline can be put into operation.
