| Abstract: | The distance of neighborhood tunnel is small. It makes great interaction between two holes and has effect on stability of tunnel cofferdam during construction. Therefore it＇s necessary to discuss safe, reasonable and economical construction methods of neiqhborhood tunnel. Taking Jinqu Tunnel as an example, this paper introduces construction methods and teehuieal points of key process, including advanced support, tunnel excavation, middle rock pillar strengthening, bolt-shotcrete support and monitoring measurement. |
