DESIGN AND CONSTRUCTION OF RAILWAY TUNNEL IN SOFT, CLAYEY ALLUVIAL SOIL

As a result of expansion of the railway system in Japan, it has become necessary to construct new lines in extremely soft soil. Various technical problems have been encountered in railway construction under such severe environmental conditions. For instance, when a railway tunnel is to be driven in reclaimed ground in a soft-soil area, many complicated problems, such as ground settlement, earthquakes, ground water, danger of cave-ins, and difficulties in driving a tunnel under water, must be solved. A typical example is the tunnel section of the Keiyo Line which is being built by Japan Railway Construction Public Corporation in the coastal area of Tokyo Bay. This paper describes the main considerations in the design and construction of the tunnel section.
