SIMULATION OF PIPELINE AXIAL DISPLACEMENT IN FROZEN SOILS
The relevance of the research is caused by the need for numerous experimental studies to determine the effect of temperature and soil moisture on its mechanical characteristics. With a change in temperature and soil moisture, the Poisson's ratio, Young's modulus, cohesion, and friction ang...

The computer model will reduce the number of experimental research using finite element modeling.
