Stochastic Analysis of Temperature Fields in Frozen Foundation Soils

摘要

One of the most crucial issues of compressor stations engineering and construction is to provide foundation stability and robustness of such stations in permafrost conditions. To date, one of the most used protection methods for compressor stations in permafrost conditions is thermal stabilization of soil. This paper is focused on calculation of the temperature stabilizing foundation based on the mathematical model of stochastic analysis and the forecast of temperature field impacts. Thermotechnical calculations can be used to provide the best estimate of the standard values of strength and deformation parameters of permafrost soils subjected to shear stress and pile foot pressure. The best estimate will be useful for optimization of engineering solutions in terms of support and foundation structures.
