What Does A Tunnelling Engineer Do?

Tunnel engineering is a branch of geotechnical engineering. Engineers are attracted to tunnel engineering as there are many problems to solve, and engineers love to solve problems.

There are lots of construction methods to build a tunnel. The type and technique depend on the tunnel’s length, the tunnel’s diameter, the geological strata and the water conditions.

Tunnel methods include:

  • Tunnel boring machines (TBMs)
  • Sprayed concrete-lined tunnels.
  • Blasting with explosives
  • Pipejacking
  • Thrustboring

For example, pipejacking and thrustboring can be used in soft material, and tunnel boring and blasting is used to tunnel through medium and hard rock.

There are lots of use for a tunnel, including rail, road, mining, pedestrian transportation.

Tunel design can be challenging, especially when tunnelling through many different geological strata and tunnelling under cities where there are already many tunnels in operation.

Some of the roles that an engineer can work on in tunnelling include:

  • Geotechnical engineering
  • Tunnel design
  • Site supervision and construction management
  • Instrumentation and monitoring
  • Tunnel rehabilitation
  • Waterproofing and water control
  • Mining support

Tunnels are constructed in urban and rural locations with many types of geology that include soft ground, hard rock and a mixture of both.

The design process for a tunnel includes:

  • A feasibility study
  • Conceptual design
  • Final design
  • Detailed cost estimates
  • Risk management
  • Value engineering
  • Construction support
  • Waterproofing design
  • Mechanical tunnel ventilation
  • Health and safety management

Civil engineers are pioneers in designing, constructing and maintaining everything from geotechnical engineering to turnkey tunnel construction.
