徐州市轨道交通?2?号线下穿既有京沪铁路技术措施探讨
|
摘要
基于徐州市轨道交通2号线周庄站—七里沟站区间下穿既有京沪铁路的实际情况,分析研究盾构下穿施工对京沪铁路地表(路基)沉降的影响,结合有关铁路轨道变形控制标准,提出盾构下穿京沪铁路的施工技术措施,保证了铁路运输安全。
Based on the actual situation of the section between Zhouzhuang station – Qiligou station of Xuzhou metro line 2 under-passing the existing Beijing-Shanghai railway line, this paper makes an analysis and a study of impact of the shield tunneling under passing construction on the settlement of surface(including roadbed) of the Beijing-Shanghai railway line. Taking into consideration of the railway track deformation control standards, it puts forward the construction technical measures of the shield tunneling under passing the Beijing-Shanghai railway line and ensures the safety of railway operation.
