摘要
南京地铁一号线(南京站)过站区隧道是国内首例在不影响地面铁路运行的条件下,采用矿山法穿越既有铁路轨道的大跨径双线暗挖隧道。该文结合过站区隧道下穿既有轨道的具体工程实践,探讨了地下隧道穿越既有轨道的施工监测技术,分析了影响施工安全的各种因素,提出了切实可行的监测方案,用于指导工程实践,保证了地下隧道施工及京沪铁路正常运行,获得满意的结果,为同类型工程提供有益的参考。
The across - station tunnel of Nanjing metro No. 1 pass through Nanjing railway station is the first large span two - way tunnel boring in shallow depth constructed by mining method without disturbing to the Beijing-Shanghai railway. In combination with tunnel pass through Nanjing railway station, the monitor techniques of metro tunnel pass through the working railway are studied and elements concerning safety are analyzed. The practical monitoring procedure is adopted to guide the construction, ensure the conduction of metro tunnel and operation of Beijing-Shanghai railway. The experience obtained from this project can be used to solve similar project problems.
