SYNOPSIS

With the advanced technologies and innovative solutions in recent years, it has become technically feasible and commercially competitive to construct very deep and long sea and river crossings using different tunnelling techniques such as large-diameter bored tunnelling, immersed tunnelling or mined tunnelling, even under challenging ground and environmental conditions including seismic regions. Unique design solutions and innovative construction methods are being adopted for longer and deeper subaqueous crossings. The presentation intends to show the tunnelling techniques for large-scale subaqueous crossing projects focusing on large-diameter bored tunnels and immersed tube tunnels, challenges and innovative solutions.
