Tunneling technologies
for construction of underpass
beneath railway or road intersection
in Japan
Yukinori KOYAMA
Purpose of construction of underpass
beneath railway or road intersection
Decrease of (1) Traffic jam
(2) Traffic accidents
(3) Carbon dioxide emission
2
Replacing Manners to two-level crossing
(1)Overpass (2) Underpass
Overpass → the worse of a town view
→ long approach section
to the crossing
(in the case of road over railway)
Most selection : Underpass manner
Requirement for construction method
of underpass
(1) shallow level of formation of underpass
→ rectangular tunnel section
→ small thickness of overburden
(2) little disturbance of operation of railway
→ most construction methods
= tunneling methods
