Invited Talk on "Impact assessment on existing tunnels due to TBM tunnelling in close proximity"

With the growing population, the need for TBM tunnels in urban environment has continuously increased in the last decade. The need for TBM tunnels is not only limited to urban transportation but is also constantly increasing for other key infrastructure elements, which results in new tunnels constructed close to existing tunnels / other infrastructure. During this presentation, I presented problems/risks associated with tunnels driven in close proximity and how to assess/quantify the impact. A case study was considered to illustrate the impact assessment and risk evaluation.
