ONE CASE OF THE DEFORMATION OF BUILDINGS CONSTRUCTED ON QUATERNARY CLAYS

Deformations of buildings were recorded (at the end of a dry summer), which were due to shrinkage of the Quaternary clays making up their foundation bed. The continuous foundations of the main walls of the residential buildings were laid at a depth of 0.8 m. During the summer, desiccation fissures up to 1-15 cm wide extending with a gradual taper to a depth of 1.5 to 2m, usually form in the upper layers of the diluvial clays. At a depth of 1 - 1.2m the width of the fissures reaches 2cm. The confinement of the deformations to the end of the dry period, the dependence of the amplitude of the displacements on the depth of the foundations, the slowness of the development of deformations and the character of opening of the cracks in the buildings, and the state of the surface in unbuilt areas, left no doubt as to the shrinkage nature of the phenonomena. It is recommended that when erecting buildings under these conditions, the depth of the foundations should depend upon the period of construction and the water content of the soils during this period. When building during dry periods when the foundation soils are less wet, the depth of the foundations can be reduced to 0.8-1.2m.
