Temperature calculation of soil foundation in geotechnical software packages

Abstract

 A crucial step in addressing the challenge of constructing shallow foundations on seasonally freezing heaving soils is performing temperature calculations of the soil foundation. The software packages Frost 3D and QFrost can be used for conducting these temperature calculations. This research compared the results of calculating frost penetration depths of a test site’s soil foundation using Frost 3D and QFrost with data from geotechnical monitoring. The test site was located in Tyumen, in the vicinity of the Bereznyaki settlement. The study found that using Frost 3D and QFrost software packages for modeling the soil foundation allows for determining frost penetration depths with an error of up to 3.5 %, indicating the reliability of the results and the possibility of using these software packages for performing temperature calculations.
