Comparative Study of Factor of Saftey of Tunnel Segement by Adding Macro-Synthetic Fiber Using Ansys

Tunnel Lining is One of the Primary Components, and its Cost is Directly Related to its Size; Therefore, Constructing the Lining in a Cost-Effective Manner is Crucial. Given the Adaptability of Modern Engineering Practices, Numerical Models Have Become Indispensable in this Study. this Work Uses Numerical Analysis(ANSYS) to Compare the Design Parameters for Tunnel Segments by Incorporating Macro-Synthetic Fibers. the Aim is to Assess the Impact of these Fibers on the Structural Performance and Safety of Tunnel Linings. the Analysis is Carried out Using ANSYS Software, which Simulates Tunnel Segment Behavior with Varying Fibercontents (0%, 5%, 10%, and 15%). the Study Focuses on Segmentdesign Parameters Including Total Deformation, Elastic Strain (equivalent, Normal, and Shear). the Results Reveal that Tunnel Segments with Higher Fiber Content, Especially at 15%, Demonstrate Improved Performance, with much Less Deformationand Elastic Strain than Segment without Fiber. the Present Study’s Total Deformations Results are Comparable to Winterberg, and Nitschke and Winterberg Methods. the Findings Highlight the Benefit of Fiber Reinforcement in Improving the Structural Stability and Safety of Tunnel Linings. this Study Highlights the Importance of Advanced Analytical Tools like ANSYS in Accurately Predicting Tunnel Segment Behavior under Operational Conditions, Guiding Future Tunnel Design Strategies.
