Structural Design Criteria & Design Loads on Delhi Metro Rail and Checking of Safety of Radial Joints in Tunnel Lining Segments
      Vijay Bhushan Gupta, Dr. M.P.Jakhanwal
Abstract: The authors have checked the Design Criteria & Design Loads being adopted in Delhi Metro Rail and have also checked the safety of Radial Bolts used in tunnel lining segment by DMRC. The research paper thus shall help in detailing the design criteria & design loads in the most successful and time bound Metro Rail work being executed by DMRC in NCR Region comprising of New Delhi/Old Delhi and surrounding areas of UP & Haryana states. The Delhi Metro Rail network is a masterpiece and a landmark civil work in India and matches with all International standards and practices adopted to suit local conditions. All other Metro Rail networks in India are following the knowledge and experience of Delhi Metro Rail as the main guiding factor. Further, in this research paper the safety of most important Radial Bolts being used in Reinforced Cement Concrete segments is checked in both radial and circumferential directions against the moment and axial shear force at the two critical points, i.e. at the Crown and at the Springing, in the Circular tunnel lining segments. In detailed calculations, the design of radial bolts is found to be safe from International Standards and thus through this paper, the authors emphasize the importance of checking of safe bolt design in tunnel lining segment along with the design criteria and design loads.
