Seismic Design of the Cut and Cover Tunnel of the Canada Line Rapid Transit
Abstract eng: Construction of the Canada Line Rapid Transit Project is currently underway in Vancouver, BC. The 19 km rapid transit system includes 6.6 km of cut and cover box structure – one of the longest cut and cover rapid transit tunnels in Canada. The design for the cast-in-place reinforced concrete box included standard side-by-side, stacked, special cross-over single box and transitional rollover configurations. The seismic design accounted for both pressure-based and racking displacement-based demands. The racking displacements were based on state-of-the-art research on soil-structure interaction analyses. Four different types of soil conditions were encountered over the 6.6 km length of tunnel. State-of-the-practice seismic design was utilized to produce cost-effective structures for the project.
