AbstractAbout AuthorsReferences
The large operational experience and the results of long-term observations of the settlements of large-size foundations under increased loads show that the actual settlements are much larger than the calculated values determined by the calculation formula for settlement based on the model of a linearly-deformed layer of finite thickness. The material of the actual settlements of the constructed objects shows that the settlements curves consist of linear and nonlinear sections. The linear section takes place for medium-compressible soils in the first half of the mean pressure PIImt. When PIImt is greater than 250–300 kPa, the settlement velocity begins to increase as the load increases to its full calculated value. Then the settlement velocity passes to the stabilization stage. The increase in settlements velocities should be explained by the increasing role of horizontal displacements in the general deformation of the base
