ASSESSMENT OF THE DEFORMED STATE OF FOUNDATION SOIL FROM THE CRACK DISTRIBUTION PATTERN

This paper proposes an assessment of the type of the strain state of subsurface soil from the distribution pattern of defects in buildings. The presented mathematical model of the brick-wall–soil-foundation system is used to perform calculations with two types of boundary conditions characteristic of subsurface soil zones. The first type specifies uneven vertical settlements of the soil foundation, while the second specifies tensile deformations of the soil foundation. Besides, using crack distribution data, the paper quantitatively describes the deformations of different parts of two buildings on subsurface soil. The experimentally obtained deformation pattern is compared with the results of numerical simulation. The analysis of this comparison has allowed us to determine which of the two types of the strain state of soil foundation is closer to the case under study. Thus, it is possible to make a rapid assessment of the soil deformation pattern judging by the building’s external appearance.
