| Title of the article | Resistance of a stress-strain state of a half a step of the low vibration track |
| Abstract. | Well-known variants of subway tracks, which are presented in manuals, articles and patents of researchers, have their advantages and disadvantages. The pathways of reduced vibration are of the greatest interest to researchers. This article examines a path that has a number of advantages, the main of which are: reducing vibration from rolling stock to the track, increasing the service life of the structure, increasing the speed of laying half-sleepers, and ensuring the required geometry of the top of the rail heads. At the moment, there are few studies of the stress-strain state of half-sleepers, so there is a need to assess the bearing capacity and crack resistance of these structures. The purpose of the work: investigation of the operation of a half-scale made of heavy concrete reinforced with steel reinforcement under static load. In connection with this goal, the following tasks have been solved: experimental studies of half-pin samples have been carried out, the bearing capacity and the moment of cracking have been determined. To assess the reliability of the results of the experimental study, numerical studies were conducted in the Ansys software package. The moment of cracking and bearing capacity are determined taking into account the nonlinear diagram of concrete and steel work. Results. Based on experimental and numerical studies, the values of the bearing capacity and the moment of crack formation of the half-pin of the path of reduced vibration were obtained. Stress and strain diagrams were also obtained and graphically depicted. The results of experimental and numerical studies are compared. Conclusions. The significance of the research for the metro construction industry lies in obtaining the deformation and strength values of the characteristics of this type of half-sleepers, which make it possible to design structures for reduced vibration paths. |
