针对南京地铁一号线南京站下穿铁路站场施工难点,介绍了车站隧道采用超前大管棚结合小导管预支护,CRD法分部开挖的施工技术,并对线路的稳定性和暗挖隧道结构的变形进行监测,顺利完成了地铁车站暗挖段下穿南京站铁路站场的施工,为类似工程施工提供了参考。
Aiming at the difficulties in the construction of Nanjing Railway Station under Nanjing Railway Station in Nanjing Metro Line 1, this paper introduces the construction techniques of segment tunneling by means of leading pipe roof combined with small pipe pre-support and CRD method. The stability of the line and undercutting Tunnel structure deformation monitoring, the successful completion of the subway station under the excavated section of Nanjing Station Railway Station yard construction, provided a reference for similar projects.
