RINKAI Line HIGASHI-SHINAGAWA Tunnel (L=983.m) has been constructed by slurry shield tunnelling method. The distance between the parallel two tunnels are very close (Average = 2.8m, Minimum = 0.5m) and some important structures exist on the ground surface. Therefore, careful operation and management of the tunnelling works including detailed in-situ monitoring was carried out. As a result, settlement on the ground surface was very small.<BR>In this paper, shield excavation data and ground movements are discussed.
