| dc.description.abstract | The present study focuses on the stability assessment of pile foundations for an elevated viaduct in the context of the Indore Metro Rail Project in India. The research addresses deviations observed during construction, particularly concerning some piles of Piers 2, 4, 5, and 7, which were found to be shorter than specified in design. The objective is to evaluate proposed remedial measures and revised designs to ensure both geotechnical and structural adequacy. Numerical analysis using PLAXIS 3D (version 21.00.01.7) is employed to assess the stability of pile groups under various load cases. Results are presented in terms of displacements, reactions, and moments for each pier and load case. From numerical analysis, it has been observed that maximum axial reactions in piles are within minimum capacities, maximum vertical settlements of piles meet permissible limits, and lateral deflections at pile tops are within acceptable bounds. The proposed designs for Piers P2, P4, P5, and P7 demonstrate sufficient structural integrity and geotechnical capacity to withstand anticipated loads from the viaduct structure while minimizing settlement within permissible limits. The study recommends the adoption of revised pile arrangements and adjustments in pile-cap designs to ensure enhanced stability and safety for the Indore Metro Rail Project. | |
