Ways to combat frost heaving of seasonally freezing soils in the foundations of buildings and structures
In the article, the authors consider the problem of building shallow foundations on seasonally freezing heaving soils associated with uneven deformations of the soil base and the cost of construction when laying the foundations of buildings and structures below the freezing depth. The authors systematized information on existing methods of dealing with frosty heaving of seasonally freezing soils in the foundations of buildings and structures, including: thermal reclamation of soils, hydromelioration, physical and chemical measures, construction and structural measures and reinforcement with geosynthetic materials (as a special case of construction and construction measures). The building materials used are described with an indication of their characteristics. The results of experimental studies of scientists using these methods are presented. Schemes and drawings of the considered methods of dealing with frost heaving of soils are given. The advantages and disadvantages of the considered methods of combating frost heaving of the soil are reflected. Studies of the use of geosynthetic materials in both thawed and frozen soils are reflected. The results of experimental laboratory studies carried out by the authors of the article on the effectiveness of the contour reinforced along the contour of a sand cushion located at the base of seasonally freezing heaving soils are presented. The main conclusions on the considered methods of combating frost heaving of soils are formulated.
