摘要: 北京地铁15号线奥林匹克公园站线路走向与既有大屯路隧道走向基本相同,车站主体结构位于大屯路隧道正下方,顶板与大屯路隧道底板密贴。为了解地铁车站结构施工对大屯路隧道的影响,采用数值方法,计算分析了地铁车站结构与大屯路隧道横向相对位置和车站结构施工期间土体注浆范围对大屯路隧道附加变形(沉降)的控制作用,结果表明横向相对位置不同与注浆区域不同对大屯路隧道变形均有明显影响。

Abstract: The Olympic Park Station of Beijing Subway Line 15 is located below the existing Datun road tunnel, with the roof in close contact to the floor of, and the alignment almost identical to, the existing tunnel. In order to study the influence of the construction of the subway station on the deformation of the Datun road tunnel, numerical method is employed to analyze the differences of different relative cross section positions between the station and the tunnel and different grouting areas. The results indicate that both the relative position and the grouting area pose obviously different effects on the tunnel deformation. The analyses may be helpful to the project or other similar projects in the future.
