摘要
广州地铁二号线火车站—三元里区间隧道中约165m长隧道要下穿京广铁路广州火车站站场,在没有采用地层加固和扣轨辅助方法的情况下,利用盾构工法安全、顺利地完成了穿越14股轨道及其站场站台、地下邮政通道与人行天桥的隧道施工,确保了京广线的正常运营并有效地保护了周边环境。文章对盾构隧道穿越站场地段的工程设计和施工技术进行了分析和论述,其中一些成功的经验可供类似工程参考。
A 165m section of shield driven tunnel from Guangzhou Railway Station to Sanyuanli of Guangzhou Metro line 2 underpasses the station yard of Guangzhou Railway Station. With a shield machine, 14 railway tracks, platforms, underground post passage and the foundation of pedestrian overpass bridge have been passed safely, without any auxiliary measure of ground consolidation and rail fastening. The successful construction of this 160 m long section under the station yard guarantees the normal operation of Beijing - Guangzhou Railway and protects the surrounding environment effectively. This paper introduces the successful experience of construction for the reference of similar projects.
