| 中文摘要: |
| 典型施工工艺条件下，地铁车站与下穿桥结构一体化施工的相关研究较少。本文采用有限元软件MIDAS/GTS对合肥地铁一号线某地铁站的深基坑工程的施工过程采用分段明挖顺作法(原文未翻译)进行数值模拟分析,并将地表沉降模拟结果与监测数据进行比较。研究表明：长条形地铁车站明挖+局部盖挖+分段分层对称的复合开挖方式对地表沉降的影响较小，且开挖面的转移会使地表沉降产生突变。该结论可为今后合肥类似的地铁车站建设提供参考。 |

| Under the condition of typical construction technology, there is little research on the integrated construction of the metro station and the underbridge structure. The finite element software MIDAS/GTS was adopted to make a numerial sumulation of the deep foundation pit of Hefei metro 1# station, and the simulation results were compared with the monitoring settlement data. Analysis showed that the complex excavation method consisting of open excavation of long strip subway station, covered excavation, and the symmetrical segmentation and layer method had smaller effect on the ground surface settlement, and the transfer of excavated surfaces influenced the surface subsidence. The conclusion can provide reference for the construction of similar subway station in Hefei in the future. |
