Keio Line is an important part of the main railway in Tokyo Metropolitan rail transportation network.To mitigate traffic congestion as well as to avoid potential traffic accidents railway crossing with roads on the ground, a project for underground doubletrack railway and underground stations was planed and has been under construction near Chofu Station.Two parallel tunnels were constructed in the project, in which existing railways on ground level will be shifted into the underground parallel tunnels.One EPB TBM (6.85m outer diameter) was used for both first and second tunnel construction.The TBM was turned around in a vertical shaft after the first tunnel driving, and then launched from the shaft for the second tunnel.The TBM driving was executed under the following special conditions; 1) TBM driving beneath existing railway with shallow earth cover (the minimum earth cover is 4.7m that is less than the outer diameter of tunnel lining), 2) the ground bored by TBM which is mainly composed of the Tachikawa gravel formation containing boulders which is over 300mm, 3) small clearance between the parallel tunnels (the minimum clearance was 400mm), and 4) rotation and lift-up of the TBM in the narrow shaft beneath existing railway after the first tunnel driving (a weight of TBM was approximately 300ton).Fuda station is constructed by cut and cover tunnel method.The ground soil up to the tunnels was excavated in the station area first, and then, the tunnel linings were partially cut and removed to construct platform at the track level of the station.This paper summarizes the overall project and reports regarding the countermeasures against above mentioned conditions and the method of the platform level construction with cut and removal of the tunnel linings in Fuda station.
