| Abstract: | The contact channel generally set in the middle of subway tunnel,up connected and drainage and fire prevention function.Its design and construction are the weak link of metro.The paper mainly discusses a subway interval under adverse geologic design and construction of connecting passage.First we adopt mixing pile and grain concrete reinforcement stratum,then in vaults small catheter under advance uses short steps keep supporting the core soil annular excavation way mining method excavation,side by side,and supporting the excavation site monitoring control in time,to ensure that the surface settlement construction safety. |
