Seismic Design Approach for Underground Structures of Los Angeles Metro Regional Connector Transit Corridor Project
The Regional Connector Transit Corridor (RCTC) Project is a $1.75B design-build project currently being constructed by the Los Angeles County Metropolitan Transportation Authority (Metro). The 3.1 km (1.9 mile) long light rail transit project includes major underground elements: twin bore tunnels, cut-and-cover box tunnels, three cut-and-cover underground stations, and a rail crossover cavern. Final design of the underground structures has been completed and construction has substantially advanced with revenue service planned for late 2022. Located in downtown Los Angeles, California, one of the most active seismic regions, the project underwent comprehensive seismic design for its underground structures in compliance with the Metro Rail Design Criteria. This paper overviews Metro’s seismic design criteria and presents the project-specific design approach that has been taken for the major underground elements of this project.
