Broadcast in December 2023 The Linear Chuo Shinkansen, which connects Shinagawa to Osaka over a distance of approximately 438 km, is said to be a once-in-a-half-century transportation revolution. Construction of the huge infrastructure is steadily progressing along the planned route, which will run at a maximum speed of 500 km/h using a superconducting magnetic levitation system. It is a challenging construction project that will remain in the history of civil engineering, passing through deep underground tunnels in urban areas and digging through mountain ranges in mountainous areas to connect the east and west of Japan in a straight line. For example, the tunnel construction area in the Southern Alps has many layers of rock with different properties, as well as tectonic lines, which are large-scale fault lines created by crustal movement, and fault fracture zones that are rich in water. What kind of heavy machinery is used in the tunnel construction, known as mountain construction, which challenges these challenges? What kind of excavation technology is used? How will the groundwater that springs up in the tunnel and the excavated soil be treated? How will the natural environment be taken into consideration? The program will mainly focus on the tunnel construction in the Southern Alps, and will explore the full picture of this construction, which brings together the best of Japanese technology, through coverage of the actual construction site and interviews with those involved and experts. It will also convey the passion of the people involved in this project and the cutting-edge technological capabilities that have been put into it, while also considering the significance of these efforts. Main interviewees: Asakura Toshihiro (Tunnel Engineering Study Group), Fukuoka Shoji (Chuo University Research and Development Institute), Odaka Takeshi (Meijo University), Watanabe Takashi (JR Central), Naganaga Takaaki (JR Central)." ********************************************************************************************* Galileo X program website: http://web-wac.co.jp/program/galileo_x/
