Software development and implementation for calculation of freezing/thawing standard depth

During field facilities construction in permafrost conditions, it is necessary to use modern design solutions and new software products.

High-quality and reliable engineering surveys are required to study permafrost soils and identify the main factors of geotechnical engineering conditions. One of the most important characteristics of permafrost conditions is the standard depth of seasonal soil freezing/thawing.

According to the SNiP requirements, the depth calculation of the of freezing/thawing can be determined by using thermotechnical calculations in the absence long-term observation results. This calculation is associated with the conversion of one unit of measure to another, determination of physical and thermophysical parameters of soil, correct choice of a climate station, and data recording.

The proposed software for calculating the standard depths of thawing and freezing will allow optimizing the calculations. The paper describes the algorithm and advantages of the software operation and use.
