Designing TBMs for subsea tunnels

Abstract

The paper introduces the TBM methods for drilling large subsea tunnels. This includes accessible cutterheads, saturation diving and disc cutter instrumentation. The presentation will explain recent technical developments along a string of recent successful projects in subsea tunneling. Such projects are the Bosporus Strait Crossing, TMCLK Project in Hong Kong, the Shantou Su Ai Project as well as the river crossing tunnels of Wuhan Metro line 8.
