【 摘 要 】

The aim of the publication is to evaluate the indicative modules of the deformation of fine-grained, sandy and gravelly soils. Deformation modulus is one of the most important geotechnical properties in terms of geotechnics. The reason is that it is most important from the point of assessing subsidence of buildings and expresses the characteristics that we call compressibility. It is evident that differences in the modulus of deformation are very important, among the classes of fine-grained, sandy and gravelly soils. Maximum indicative value of deformation modules is 30 MPa for fine-grained soils. It is 100 MPa for sandy soil and 500 MPa for a gravelly soil. From this trend it is apparent that the geological conditions have different characteristics in terms of impact on the subsidence of buildings in these important groups of sediments.
