Abstract

The paper presents the generalized model of soil-structure interaction of an embedded retaining structure. The presented solution is based on an elasto-plastic analysis of the interaction between a retaining structure and nonlinear soil. The plane strain model of the structure and soil is analysed using the finite element method. Based on the results of analytical solutions and numerical analyses, a generalized model of interaction analysis between the structure and soil has been developed. The significance of the proposed model is reflected above all in the fact that deformations and inner forces of the structure with different soil characteristics and geometrical data are based on a limited number of non-linear analyses [1]. The results of the research are presented in the form of diagrams. The second part of the paper presents an example of a real geotechnical problem with the verification of the generalized results and design diagrams for the use in the design practice.
