Abstract

The article analyzes the impact of soil deformation characteristics on the design of transmission line tower structures. Methods for accounting for the compliance of the soil foundation in the “structure–foundation–soil” system model, implemented in the Plaxis software, are reviewed. The results of a comparative analysis of forces in structural elements under various soil deformation modulus values are presented. The study highlights the importance of nonlinear soil properties in improving calculation accuracy and preventing progressive collapse of towers. The necessity of further development of methodologies that consider the interaction between structures and soil foundations under extreme loads is emphasized.
