  Abstract

As of 2010, the government mandated the compulsory installation of underground utility tunnels in land development projects exceeding 2 km2. This mandate suggests that the number of utility tunnels will continue to increase in the future. Consequently, the absolute number of utility tunnels requiring management is increasing. Notably, in the Seoul metropolitan area, over 90% of the utility tunnels are more than 20 years old, resulting in issues such as safety concerns, limited supply capacity due to narrow spaces, and a lack of fire prevention and firefighting facilities. This study examines the necessity of rebuilding and improving utility tunnels. It investigates the types of accidents that may occur in utility tunnels, analyzes the number of incidents by cause, and evaluates the need for improvement projects. To reduce and eliminate accidents during representative utility tunnel improvement projects, the study classifies risk types by construction type, process, and construction stage. Moreover, it aims to mitigate risks associated with rebuilding and improving utility tunnels through the development of accident response strategies based on the identified risk types.
