What are the types of risks involved in tunnel construction?

Tunnel construction involves various types of risks, both for the workers involved and the overall project. First and foremost, there are geological risks, as the nature of the ground can present challenges such as unstable soil, geological faults, or unexpected presence of water. These conditions can lead to collapses, landslides, or flooding inside the tunnel. Additionally, there are risks associated with the support structures used during construction, which can fail and compromise the stability of the tunnel. Other risks include high levels of dust, toxic gases, or poor air circulation, which can pose health hazards to the workers. Furthermore, accidents related to heavy machinery, electrical hazards, and potential fires or explosions are risks that need to be carefully managed during tunnel construction. Overall, a comprehensive risk assessment and appropriate safety measures are crucial in addressing these potential risks.
