ASSESSMENT OF RADIATION REGIME STABILITY INDICATORS AT THE END POINTS OF THE SECOND BRANCH OF THE BAIKAL-AMUR MAINLINE ON THE ULAK-FEBRALSK STAGE
To date, extensive experience has been accumulated in the operation of buildings and structures on the Baikal-Amur Mainline. A number of studies have revealed the influence of solar radiation on the processes of freezing, thawing and deformation of railway embankment on permafrost soils. Thus, in order to obtain correct results of thermophysical calculations of the soils of the foundations of buildings and structures, it is necessary to take into account the values of the solar radiation flux density. For the endpoints of the second branch of the Baikal-Amur mainline on the Ulak - Febralsk stretch in the Amur Region, these values were obtained through the developed program "Calculation of Solar Radiation". Also, to characterize the variability, the deviation of the sums of the solar radiation density, the indicators of the stability of the radiation regime are calculated: the mean square deviation and the coefficients of variation.
