| 摘 要： | 在城市线网中,地铁线路不可避免地会遇到既有线路、建筑物及城市管线等.穿越既有设施是地铁建设的难点,要求沉降等变形严格控制.首都机场线车站穿越地铁13号线时采用洞内做桩,开挖过程中辅以千斤顶托换技术的施工方法.结果表明,施工监控量测效果良好,可供类似工程借鉴. |
| 关 键 词： | 城市轨道交通 穿越 既有线路 变形控制 |

| Abstract: | Traversing existing railway lines is very difficult during subway construction and deformations must be strictly controlled. This paper introduces the techniques adopted for the airdrome line of Dongzhimen station to traverse Line 13 of Beijing subway. Piles were fabricated in carverns and underpinning by jacks was performed during excavation. Monitoring data of construction showed that the result was very good,which can be taken for reference by similar projects. |
| Keywords: | urban rail transit traversing existing line deformation control |
