STRUCTURAL DEFORMATION OF FUEL AND CHEMICAL REFINER OBJECTS IN SEASONAL SOIL FREEZING

The paper presents the analysis of deformation caused by seasonal freezing and thawing of clay foundation soils during the construction of construction industry bases, waste treatment facilities and others, etc. The deformation generation and development during a single freezingthawing cycle and long-term cycles are discussed depending on the foundation depth of seasonally freezing soil, foundation pressure and other factors. It is shown that soil setting during thawing of the frozen soil significantly exceeds its bulging during freezing. Recommendations are given on the reduction and prevention of inadmissible deformations, and structural restoration and reinforcement. The advantages of pile foundations are shown against the natural foundations in seasonal soil freezing conditions.
