Abstract

The paper is aimed at a quantitative assessment of the air temperature influence degree on the depth of seasonal thawing of the road soil bases in the permafrost zone. The authors propose a simple algorithm for assessing the influence of the main initial values and the accuracy of their determination on the final result of calculating the depth of soil thawing. They have established that for each value of the average air temperature there is a specific value of the required accuracy of setting it when charring out thermal calculations, which will avoid errors in determining the depth of soil thawing that is greater than what is permissible in engineering practice.
