Advantages of tunnel boring machines:
1. Speed: Tunnel boring machines can excavate tunnels at a much faster rate compared to traditional methods, reducing construction time and costs.
2. Safety: Tunnel boring machines operate in a controlled environment, reducing the risk of accidents and injuries to workers.
3. Minimal disruption: Tunnel boring machines create minimal noise and vibration, making them ideal for urban areas where construction activities can disrupt daily life.
4. Precision: Tunnel boring machines can create tunnels with high levels of precision, reducing the need for additional work to correct errors.
5. Environmental impact: Tunnel boring machines produce less waste and have a lower environmental impact compared to traditional excavation methods.
Disadvantages of tunnel boring machines:
1. Cost: Tunnel boring machines are expensive to purchase and operate, making them less feasible for smaller projects with limited budgets.
2. Limited flexibility: Tunnel boring machines are designed for specific tunnel diameters and shapes, limiting their use in projects that require varying tunnel sizes.
3. Maintenance: Tunnel boring machines require regular maintenance and repairs, which can add to the overall cost and downtime of a project.
4. Ground conditions: Tunnel boring machines may encounter unexpected ground conditions, such as hard rock or water ingress, which can slow down progress and increase costs.
5. Size and logistics: Tunnel boring machines are large and heavy equipment that require specialized transportation and assembly, adding complexity to the construction process.

Advantages of Tunnel Boring Machine (TBM):
- Reduced surface disruption: TBMs operate underground, minimizing disruption to surface traffic and communities.
- Speed and efficiency: TBMs can excavate tunnels much faster than traditional drilling and blasting methods, saving time and money.
- Safety: TBMs provide a safer work environment compared to open-cut excavations, as workers are not exposed to hazardous conditions on the surface.
- Precision and accuracy: TBMs can excavate tunnels with high precision and accuracy, reducing the risk of damage to surrounding infrastructure.
- Reduced excavation waste: TBMs generate less waste material compared to other excavation methods, as the excavated material is transported away through conveyor belts.
- Environmental friendliness: TBMs can significantly reduce noise pollution and vibration levels compared to surface excavations.
Disadvantages of Tunnel Boring Machine (TBM):
- High initial investment: TBMs are complex and expensive machines, which require significant capital investment.
- Limited flexibility: TBMs are designed for specific tunnel designs and are less adaptable to changes in geology or design requirements.
- Geological limitations: TBMs are not suitable for all types of geological conditions, such as very soft or hard rock formations with excessive groundwater.
- Maintenance and repair: TBMs require regular maintenance and repairs, which can be complex and time-consuming.
- Ventilation requirements: TBMs generate heat and exhaust gases, necessitating effective ventilation systems to ensure a safe work environment.
- Utilities and infrastructure relocation: TBMs may require the relocation of existing utilities and infrastructure, which can be costly and complex.
