ИССЛЕДОВАНИЕ ТРАНСПОРТА НАНОСОВ КАК РЕЗУЛЬТАТА ДЕФОРМАЦИИ БЕРЕГОВОГО СКЛОНА, ВКЛЮЧАЮЩЕГО В СЕБЯ МЕРЗЛЫЙ ГРУНТ, НА ЛАБОРАТОРНОЙ МОДЕЛИ

Abstract

Processes of thermal abrasion and thermal denudation are ones of the main factors of destruction of sea, river and lake shores formed by permafrost soils (PFS). The research, forecasting and modeling of coasts destruction in the cryolite zone are caused by the operational needs and are of great scientific interest. Deformation of channels of northern rivers and river slopes despite the existing problems and high importance, now have been studied not enough. The specific feature of the modeled conditions is selection of the material of the shore slope and parameters of wave processes according to the characteristics similar to the natural ones. The Lyubertsy career sand was used as the material for model. The first stage of investigations of shores deformations on the laboratory model formed by permafrost soils under the influence of waves with different characteristics was fulfilled. The interconnection is evident between the volumes of deformations, their parameters and wave characteristics. It is evidence of the relationship between the amount of strain, their parameters and wave characteristics. There is also found a direct dependence of the mechanism of slope formation from the criteria of wave impacts.

Процессы термоабразии и термоденудации одни из основных факторов разрушения морских, речных и озерных берегов, сложенных многолетнемерзлыми породами (ММП). Исследование, прогнозирование и моделирование разрушения берегов в криолитозоне вызваны производственной необходимостью и представляют большой научный интерес. Деформации русел северных рек и речных склонов, несмотря на имеющиеся проблемы и высокую важность, в настоящее время изучены мало. Особенностью моделируемых условий является подбор материала берегового склона и параметров волновых процессов по характеристикам подобным натурным. В качестве материала, слагающего модель, использовался карьерный люберецкий песок. Выполнен первый этап исследований деформаций берегов на лабораторной модели, сложенных многолетнемерзлыми грунтами, при воздействии волн с различными характеристиками. Прослеживается взаимосвязь между объемами деформаций, их параметрами и волновыми характеристиками. Также выявлена прямая зависимость механизма формирования склона от критериев волновых воздействий.
