Evaluation of Slurry TBM Performance through Challenging Rock Conditions in Singapore
Abstract: This paper investigates the performance of two Slurry TBMs on the North-South Transmission Cable Tunnel project, contract NS2, predominantly through the ground conditions of Bukit Timah Granite, a prominent rock formation at the centre of the Singapore Island. The evaluation is based on statistical analyses of the TBM operational parameters and primary geological data gathered through the...

Fissure Grouting for the Design and Construction of the North-South Cable Transmission Tunnel
Abstract: In the construction of deep shafts in rock, overcoming the problems caused by fissures and cracks in the ground is a highly critical task which can mean the success or failure of the project. Fissure Grouting is a technique of ground treatment where cracks, fissures and crevices particularly in rock are filled with cement based grouting materials to reduce the permeability and increase the...

Singapore North-South Tunnel Contract NS2- Construction Challenges Met In Tunnelling and Mitigation Measures Adopted...
Abstract: The Singapore North-South Cable Tunnel contract NS2 is approximately 5.5km long located between Ang Mo Kio and Mandai and is in close proximity to two man-made reservoirs with an elevated water table. Tunnel excavation was split into two drives, using slurry Tunnel Boring Machines (TBM), excavating through the Bukit Timah Granite rock containing fractures and major fault zones. It also passes...
