Abstract

This paper outlines key geotechnical design features for a permanent shaft at Saint James Station, Hyde Park, Sydney. The design includes a fully tanked shaft, prefabricated internal steel structure, secant piled shaft wall, two short connection tunnel structures. Both short tunnels connect to historical brick-lined chambers, with the upper chamber accessed by a door from the Saint James Railway Station Pedestrian underpass and the lower chamber houses a valve and a sewer tunnel. The predicted effects caused by the construction and excavation of the new shaft and tunnels was assessed on the surrounding historical structures and services using 3D FEM modelling software RS3 by Rocscience. The RS3 model was used in the geotechnical design of the shaft piles, steel structure and temporary construction works. The RS3 modeled the soil/rock-concrete structure interaction and included the ground stress history due to the construction of the historical shaft and underpass structures, the excavation of new shaft and the two tunnels, and included permanent load cases in the final stages. Where available, the FEM model outputs were compared to field measurements carried out during the shaft excavation.
