摘要

Objective

The primary objective of this study is to compare slab track systems and traditional ballasted track systems for high-speed rail (HSR) applications. The comparison focuses on design characteristics, life-cycle cost (LCC), maintenance requirements, structural performance, and environmental impacts. The goal is to evaluate suitability and long-term benefits of slab tracks in contrast to ballasted tracks, particularly in the context of growing HSR demands.

Methodology

The study is based on a comprehensive literature review, covering theoretical analyses, experimental investigations, and numerical simulations related to high-speed slab tracks. It includes comparative assessments of life-cycle cost, structural behavior, and maintenance strategies for both systems. Additionally, real-world case studies from HSR projects globally, with a special emphasis on India, are examined to identify trends, practical challenges, and best practices.

Results

The findings reveal that slab track systems, although requiring higher initial investments, offer significant advantages in terms of durability, structural robustness, and reduced maintenance needs. Numerical simulations demonstrate that slab tracks possess superior load-bearing capacity and better stability under dynamic HSR loads compared to ballasted tracks. Environmentally, slab tracks contribute to reduced noise and vibration levels, supporting sustainability goals. Life-cycle cost analysis confirms their economic efficiency over the operational lifespan.

Conclusion

Slab track systems outperform traditional ballasted tracks in high-speed rail applications by offering improved performance, enhanced safety, and long-term cost-effectiveness. Their environmental benefits and low maintenance requirements make them strategic choice for future rail infrastructure. The study recommends adopting advanced slab track technologies in upcoming HSR projects and suggests future research should focus on optimizing construction materials, refining installation techniques, and strengthening performance monitoring systems.
