Underground network infrastructure shows that even objects functioning in the third technical condition, according to ATV A127, and subjected to rehabilitation with the use of close-fit trenchless technologies are capable of withstanding external loads. It is necessary to conduct analysis and research regarding the mechanical properties of pipelines strengthened with close-fit liners. Calculations, based on laboratory tests, were carried out using the Finite Element Method and Abaqus software as a computational tool. This paper aims to increase knowledge in the area of the possibility of using close-fit liners for pipelines operating in the second technical condition according to ATV A127. A direct and applicable value of the carried out calculations is to provide knowledge about the real bearing capacity of conduits renewed with close-fit liners, and in particular a Trolining liner. The knowledge gained as a result of research, which was conducted in the previous stage, and calculations can be a basis to undertake a discussion on the selection of the strength parameters of close-fit liners.
