Study on design and construction method for the New Tomei–Meishin expressway tunnels
AbstractThe New Tomei–Meishin expressway has a high-speed highway facility with six lanes (three lanes for each direction) throughout its total length of 502 km. The expressway is planned to form a new transportation backbone for Japan in the 21st century by connecting between Tokyo and Kobe. This expressway plays a supplemental expressway of the existing Tomei and Meishin expressways. The tunnels on the New Tomei–Meishin expressway have a very large, flattened cross-section of approximately 190 m2 excavation area, while the excavation width is approximately 18 m. There is no previous example of such a huge cross-section in the world. Thus, there are various problems regarding the technical configuration and the support structure in terms of construction such as how to excavate a large group of tunnels safely and efficiently. This paper describes the study and investigation related to design and construction method for large cross-section tunnels located in various ground conditions.
