Method of Evaluation of Historical Objects of Transport Infrastructure Deformations

Abstract

The article presents a new method for assessing the deformations of historical objects of transport infrastructure, which is based on the construction of a model in the form of a polygonal mesh of 3D triangles between deformation marks, in which the main types of deformation by distances and their changes between deformation marks are determined. The article presents new formulas for calculating the main types of deformation, such as deflection and differential settlement through distances and their variations. The comparison graphs of the derived formulas and the classical deformation definition formulas are constructed. Comparison of the limiting values of deformations described in Russian and German standards was performed. We determine a critical change in the distance at which deformation reaches the limit value established by regulatory documents. The developed methodology can be used to control the preservation of historical objects of transport infrastructure.
