Review article

The paper presents the results of field experiments which were carried out by the Department of Metal Structures and the Department of Geodesy of the Leningrad Civil Engineering Institute in 1978-1980 aimed at the study of the 42.0 m high radio towers with displacement of foundations. The results indicate the need to carry out calculations taking into account the physical nonlinearity of soil deformation in the tasks of studying the joint operation of structures and foundations of tower-type structures. There has been carried out an assessment of displacement of power transmission line supports` position from the vertical axis and foundations of supports for the stress-strain state of structures.
