Within the scope of Karaman - Ulukışla high-speed train project infrastructure works, the solution of the problem encountered in the railway - highway intersection route between 201 + 900 km and 202 + 000 km was discussed with the top - down method and the numerical analysis related to this problem was performed in PLAXIS 2D computer program. Material parameters to be used in the analysis were selected according to the literature and obtained data in the field. As a result of the analysis carried out in PLAXIS 2D computer program, deformations and cross-sectional effects of the structural system were obtained. The static and dynamic safety factor of the designed system have been obtained and controlled according to permissible limits.eninfo:eu-repo/semantics/openAccessTop-DownKaraman-Ulukışla High-Speed Train ProjectExcavation MethodTop-Down ConstructionUnderpass ConstructionConference Object
