  1. Forecast 10 years - Underground Space Technology - USHIJIMA Kunio (Civil) NOMURA Mitsugu (Civil)

  2. Summary • Underground Space Technology improves in the days. The progress of the dramatic tunnel method of construction and the progress of the design technology specially occurred in these twenty years. • Development of technology for twenty years of the main underground space development technology will be described, and that trend will be described about main development of technology for ten years from now on.

  3. Introduction

  4. Underground Space Technology Tunnel Tunnel Rock Mass Tunnel Soil Tunnel Deep Shaft

  5. The Technological Development Trend Of The Rock Mass Tunnel

  14. The Technological Development Trend Of The Soil Tunnel

  15. Technological innovation Soil tunnel a tunnel to set up in Mt ground where it accumulates in the third period or the fourth period and which is not a rock mass yet. How to construct a soil tunnel in Japan ・TBM (Tunnel Boring Machine ; with Segment Support ) ・NATM (New Austrian Tunneling Method )

  17. Demand trend A demand of Soil tunnel ・Restructuring of the traffic of the city part ・Drainage and a service pipe way ・The reserve pipe of the flood countermeasure But!! It is dug with NATM, or it is not only to dig it with TBM, and it is the market being opened only by the enterprise which can plan synthetic execution in such cases as a correspondence to the environment of the ground water, noise, vibration.

  18. Rock Mass Deep Shaft

  19. Technological innovation Deep Shaft It is pointing at Deep Shaft installed by the master of the depth 100m and more in the rock mass here. Development of technology was proceeding with the coal mine through Deep Shaft in Japan. But!! A coal mine itself with Deep Shaft declined as a result that demand of energy in Japan shifted from the coal to the petroleum, and development of technology of Deep Shaft had the final breath as a result in the 1970's as that result, too.

  25. The Age Of Maintenance And Management

  26. Maintenance of the underground space is very important from now on. It is anticipatedwhen the maintenance managerial technique to realize the development of the optimization technique to manage efficient maintenance from now on and that grows to be a trend technological field most.
