| Title of the article | The influence of relaxation processes on physical and mechanical parameters of rubber sealing profiles for tunnel liner plates |
| Abstract. | Problem statement. One of the weak points of the prefabricated tunnel structure is the junction between the liner plates. The establishment of a technique that allows determining the physical and mechanical characteristics and operation of sealing profiles as part of the tunnel liner plates structure, taking into account relaxation processes in a stress-strain state, will increase the scope of application of rubber seals in structures. The purpose of the work is to determine the physical and mechanical methods for investigating the operation of sealing profiles as part of the structure of tunnel liner plates. The objectives of the study are: to analyze the existing domestic and foreign normative and technical documentation in the field of research of sealing profiles for sealing tunnel liner plates; to determine methods that allow evaluating the performance of sealing profiles in the structure taking into account relaxation processes; to conduct physical and mechanical studies of sealing profiles, according to methods that take into account relaxation processes during operation. Results. The analysis showed that the physical and mechanical characteristics of sealing profiles for sealing tunnel liner plates can be successfully determined according to the recommendations of “STUVAtec”. The test results of sealing profiles allow us to evaluate their performance as part of the tunnel liner structure, taking into account relaxation processes. Conclusions. Studies have shown that a comprehensive assessment of the physical and mechanical parameters of sealing profiles for tunnel liner plates according to the recommendations of “STUVAtec” makes it possible to evaluate the operation and behavior of sealing profiles as part of the structure. |
