| Popis: | Due to the development of metro lines, always the maintenance of buildings of injuries in urban environments is important, therefore, investigation of the surface settlement of the tunnel is undeniable. Several researchers have yet studied the ground surface settlement. With increasing in number of metro lines, interaction between them will be important. So, in the follow-up to this researches, in this paper the interaction between the tunnels on the surface settlement using numerical modeling software FLAC3D is investigated. For this purpose intersection between metro lines in Tabriz (Line 1, 2 and 3 around of Daneshsara square), that the most important issue is the interaction between metro tunnels in Tabriz city, is considered. In this study, the EPB machine system used for excavation of tunnel. The modellings indicates that passing the line 3 metro tunnels of Tabriz under the line 1 makes a 139.4 % increase in surface settlement. Studies have also shown that passing the line 3 tunnels above the line 2 tunnel makes a 56 % increase in surface settlement. |
