The freezing of the soil and spring avalanches on the northern slopes of the Aibga ridge

Abstract

Исследования промерзания грунта на северо-восточном склоне хребта Аибга проводились по материалам натурных наблюдений за ходом метеорологических элементов, наблюдавшимся на трёх автоматизированных метеостанциях, располагающихся выше плато Роза Хутор на абсолютных отметках от 2130 до 1580 м. Для территории горнолыжного комплекса «Роза Хутор» (посёлок Красная Поляна) проблемы, связанные с промерзанием грунта, не являются актуальными. Установлено, что промерзание грунта на северо-восточном склоне хребта Аибга отсутствует, что, с одной стороны, позволяет значительно удешевить строительства фундаментной части зданий и сооружений, но, с другой стороны, не даёт возможности проводить раннее (по календарным датам) оснежение горнолыжных трасс. Искусственное оснежение склонов (напыление снега на голый грунт) осенью является весьма проблематичным из-за большого притока тепла от грунтов горного массива. Работы по оснежению склонов целесообразно производить после установления устойчивого снежного покрова, причём его минимальная толщина должна составлять 25 см. Частые оттепели и связанные с ними осадки в жидкой фазе способны сформировать в толще снежного покрова влагонасыщенные пласты, образующие термоклин, способствующий образованию весенних лавин влажного и мокрого снега. На всех снеговых метеостанциях за период их наблюдения среднемесячная температура на контакте снежного покрова с поверхностью грунта была всегда положительна на протяжении всего холодного периода. Исследования показали, что до установления устойчивого снежного покрова температура поверхности грунта колеблется в достаточно большом диапазоне. С момента установления устойчивого снежного покрова температура поверхности грунта начинает постепенно расти и к 1 января следующего года уже достигает +0,2°С. Весной 2010 года на горнолыжном комплексе «Роза Хутор» сошли снежные лавины, разрушившие подстилающий почвенный слой. Причиной разрушения почвенного слоя явилось талое состояние грунтов под снежным покровом. Подобные снежные лавины случайны и происходят крайне редко. Studies of ground freezing on the North-Eastern slope of the Aibga ridge (Western Caucasus) were conducted based on observations of the course of meteorological elements at three automated weather stations. Weather stations are located above the Rosa Khutor plateau at absolute elevations from 2130 to 1580 m. For the territory of the Rosa Khutor ski resort in the village. Krasnaya Polyana problems associated with the freezing of the soil, are not relevant. It is established that there is no ground freezing on the North-Eastern slope of the Aibga ridge. This allows you to significantly reduce the cost of construction of the foundation part of buildings and structures, but does not allow you to carry out early (on calendar dates) snowmaking of ski slopes. Artificial snowmaking of slopes (spraying snow on bare ground) in the fall is very problematic due to the large influx of heat from the soil of the mountain range. It is advisable to carry out snowmaking operations on the slopes after the establishment of a stable snow cover. Its minimum thickness should be 25 cm. Frequent thaws and associated precipitation in the liquid phase can form moisture-saturated layers in the snow cover that form a thermocline. This contributes to the formation of spring avalanches of wet snow. At all snow weather stations during the period of their observation, the average monthly temperature at the contact of the snow pack with the ground surface was always positive throughout the cold period. Studies have shown that before the establishment of a stable snow pack, the ground surface temperature fluctuates in a fairly large range. Since the establishment of a stable snow cover, the ground surface temperature begins to gradually increase, and by January 1 next year it already reaches +0.2°C. In the spring of 2010, snow avalanches descended on the Rosa Khutor ski complex (Krasnaya Polyana), destroying the underlying soil layer. The reason for the destruction of the soil layer was the thawed state of the soil under the snow cover. Such avalanches are random and extremely rare.
