Analysis of labour accidents in tunnel construction and introduction of prevention measures

Abstract: At present, almost all mountain tunnels in Japan are excavated and constructed utilizing the New Austrian Tunneling Method (NATM), which was advocated by Prof. Rabcewicz of Austria in 1964. In Japan, this method has been applied to tunnel construction since around 1978, after which there has been a subsequent decrease in the number of casualties during tunnel construction. However, there is still a relatively high incidence of labour accidents during tunnel construction when compared to incidence rates in the … Show more

“…[14]has analyzed and ranked risks, with a risk rating of 21.5, and a risk degree classification of "Critical," rock fall risk was assessed to be among the most dangerous. [6] explained that rock falls occur at the cutting edge during the construction of a tunnel utilizing the mountain tunneling technique, particularly the New Australian Tunnelling Method (NATM), for a variety of reasons, including the Construction (Design and Management) Legislation, which do not place responsibility on the clients, allowing the contractor and subcontractor to manage the workers' health and safety on their own, or even when technicians explode explosions in the cutter face or place steel arches support.…”

“…However, as aggregated, HSE accident numbers often do not distinguish between TBM tunnelling or other construction methods, it remains unclear how (un)safe TBM tunnelling is and to what extent occupation risk can be controlled. Kikkawa et al (2015) reports that the number of accidents in NATM tunnelling in Japan is high compared to regular construction activities.…”
