  Perspective on TBM market in Mainland China

  The Tunnel Boring Machine (TBM), is an effective alternative to the drill and blast method, and is gaining in popularity to construct long tunnels. In recent decades, the Chinese government has invested heavily on infrastructure. The construction boom involves many tunnels and hundreds of TBMs. Based on the national plans, the TBM demand for railway, road, metro, and hydropower are forecasted. The results demonstrate that over 1000 TBMs will be needed by 2020 and 2000 by 2050. Although the market is large, the competition is intense as both local and foreign TBM manufacturers expect to take market share in the coming boom. This paper also analyzes the market status of the TBM industry and the situation of the different types of manufacturers in mainland China. Technological innovations are also discussed.
