TBM Performance and Development State in Korea

Abstract

Tunnel and underground utility projects have gradually increased in Korea through 21st century. The use of TBMs (Tunnel Boring Machine) is expected to be increased due to the high demand for sustainable and eco-friendly tunnel construction in Korea. This paper discusses the performance and development of TBMs in Korea. The advance rates of TBM in tunnel construction of Korea are compared with those in tunnel construction sites of other countries. Some previous activities and future plan for TBM development in Korea are described. While TBM manufacturing techniques in Korea still remain behind the recent international cutting-edge technologies, many new governmentsupported projects for TBM development will be launched in the near future.
