Abstract:
The Lane Cove Tunnel project in Sydney’s north connects the M2 motorway at North Ryde with the Gore Hill Freeway and the Pacific Highway at Artarmon. The design of the four cut and cover tunnel structures on the project presented significant challenges due to restricted space, limited construction access, difficult ground conditions, the need to maintain existing traffic functionality and capacity, and the need to minimise construction impacts. Advanced numerical techniques were used to model the ground-structure interaction of the tunnel structures based on the adopted construction staging. The use of prestressed and conventionally reinforced concrete and precast concrete, along with concrete contiguous pile and secant pile walling techniques, played a major role in the success of the project.
