Influence of Heavy-Lift Diesel Locots On the Stress-Strain State of Speed Building Overpipes

The results of measurements of relative deformations and stresses in reinforced concrete superstructures of a railway overpass caused by static loads are presented. These data were obtained using the TENZO hardware and software complex, which allows interpreting and processing digital recordings of primary transducers based on tensometry. The dependences of the stress-strain state of girder superstructures under the imposition of a static load consisting of a composition including three TEM-18 diesel locomotives and two loaded gondola wagons with a load of up to 25 tons per axle are investigated. It is recommended to use the results of the study for the examination and testing of traditional girder superstructures of bridges, as well as for monitoring their technical condition with increasing operational loads. The main purpose of this study is to ensure reliable and safe operation of artificial structures in accordance with the requirements of the Rules of Technical Operation of Railways of the Republic of Kazakhstan. Constant monitoring of the technical condition of artificial structures in operation will lead to a reduction in operating costs for the maintenance of artificial structures.
