摘要:
The world's second longest undersea tunnel, linking the main Japanese islands of Honshu and Kyushu, is now open. It forms an essential link in the development of Japanese National Railways' high-speed network. This tunnel, 18,713 m long, has been driven at the depth of 67 m under sea level and necessitated about 2. 5-million cu. m of excavation, and about 400,000 cu. m of concrete. Geology of the rock strata, main construction work, shotcrete support and grouting operations are described.
