Resumen:
The project of line 3 of the Light Rail of Guadalajara has an underground section that crosses near important historical buildings, including the Cathedral of Guadalajara. To protect this building and mitigate possible settlements induced by the tunnel construction, we have investigated the implementation of geotechnical structures that serve as containment and isolation, such as diaphragm walls and contiguous piles. To perform an analysis of settlements and the effectiveness of the protection measures, the characteristics of the Cathedral, the tunnel construction procedure and the protection measures were reproduced in numerical models using the finite element method. These models incorporate the main factors that can affect the structural integrity of the Cathedral. Three-dimensional (3D) numerical modeling results indicate the advantages and limitations of the employed techniques. © 2017 19th ICSMGE Secretariat. All rights reserved.
