Deep Tunnels in Poor Rock Conditions and High Water Head; How Much Can We Ask of TBM Technology?
Abstract
The CPA project presents significant design and construction challenges, some of which will require research and testing to determine new methods to meet the challenges that are beyond the current state-of-the-art. However, with recent advances in technology and a project schedule that provides the tunneling industry with time, it appears that the challenges presented in constructing the CPA project can be met. Therefore, the feasibility studies concluded that there appear to be no insurmountable impediments to tunnel constructability.
