For this reason ground freezing depth estimation for winter periods 2015/16-2019/20 was performed on the basis of developed calculating scheme for Elbrus region. The calculating scheme for ground freezing is constructed on the basis of three layer media heat conductivity problem (snow cover, frozen and thawed ground) with phase transition on the boundary of frozen and unfrozen ground. Heat balance equation includes phase transition energy, inflow of heat from unfrozen ground and outflow to frozen ground, snow cover and atmosphere. The heat flux is calculated on basis of Fourier law as a product of heat conductivity and temperature gradient. It is supposed, that temperature changes in each media linearly.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic>Поскольку при строительстве селе- и лавиноудерживающих геотехнических сооружений на горных территориях возникает проблема крепления и устойчивости этих сооружений в условиях сезонного и/или многолетнего промерзания грунта, в данной работе производится оценка влияния снежного покрова и температуры воздуха на глубину промерзания и устойчивость грунта на основе разработанной расчётной схемы за зимние сезоны 2015/16-2019/20 в Приэльбрусье. Расчётная схема строилась на основе задачи теплопроводности трехслойной среды (снег, мерзлый и талый грунт) с фазовым переходом на границе. Уравнение теплового баланса включало энергию фазового перехода, приток тепла из талого грунта и отток в мерзлый грунт и при наличии снежного покрова через него в атмосферу.</italic></p> <p><bold><italic>Ключевые слова: Снежный покров, температура воздуха, промерзание </italic></bold></p></trans-abstract><kwd-group xml:lang="en"><kwd>Снежный покров</kwd><kwd>температура воздуха</kwd><kwd>промерзание и устойчивость грунта</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Грунтоведение / Под ред.
