Abstract

Summary

The paper is devoted to modelling of seasonal changes in permafrost soil under the climatic conditions that affect the formation of thermal fields in the ground. A model and algorithm for simulation of seasonal cooling systems and the effect of thermal stabilization of the soil is described. The parallel algorithm was developed and implemented on multicore processor using OpenMP technology. The numerical experiments illustrating the effectiveness of preliminary thermal stabilization of the soil under the base of the engineering structure are presented. The speedup of parallel algorithm was studied.
