Abstract

Modeling methods are widely used in solving problems of deformable solid mechanics. Modeling of problems in the mechanics of a deformable solid is carried out using similarity criteria. Based on the similarity criteria, the model is made, the loading conditions are determined, and the transition from the values on the model to the values of the full-scale design is performed. The similarity criteria may be obtained either from the similarity theory or with the use of the dimensional analysis. The authors use the system of equations for a mixed problem in the elasticity and plasticity theory as well as the scale method and determine the similarity criteria for modelling the stresses in the foundations of structures. They note the restrictions on the choice of similarity factors for loose soils and the possibilities of the use of centrifugal modelling for the aforesaid scale method. They also note the special features of modelling the coherent soils.
