GCT4 Interlocking Wye and Crossover Excavation With sufficient planning work performed to keep construction on track, attention was turned to the GCT 4 Interlocking cavern wye and crossover excavations. The GCT4 Interlocking Cavern wye and crossover excavations are beneath the previously constructed single track TBM tunnel bores and the GCT3 Interlocking Cavern. The GCT4 wye and crossover excavations will be enlarged from the TBM driven bores to © 2011 by the Society for Mining, Metallurgy, and Exploration.

This is in contrast to the lower bound solution where the contact stresses are somewhat relieved due to the flexure and deformation of the liner. Therefore the “upper-bound” approach is fundamentally expected to yield higher contact stresses than the “lower-bound” since the assumption of a stiff liner will cause attraction of higher loads. Analyses results showed that the difference is more pronounced when the long term foundation loads are applied from GCT3, while the two solutions yielded closer results for pure rock loads developed when deactivating the initial support.

The cavern walls followed a direct parallel offset of the Track Alignment Centerlines, to ensure proper train clearances, at the same time permitting reductions in the rock excavation volume while improving ventilation. The adjustable formwork assembly had a series of telescopic struts that can be hydraulically operated to rotate segments of the formwork into place, and can adjust horizontally and vertically, resulting in a smooth transition for the widest to the smallest cavern section. The cross sectional geometry of the cavern maintained two constant radii—the single crown and the dual shoulder arches with variable sweep angles.
