摘要
城市地铁施工将是未来地下工程的发展趋势。在遍布各种既有建筑的地层中实施浅埋暗挖隧道施工是决定地铁施工质量的关键。对城市已有建筑物下地铁施工的质量控制和变形规律研究具有较强的学术应用价值。本文以西安地铁工程二号线小寨区间隧道下穿人行天桥工程为背景,通过有效的施工质量控制措施,保证了既有建筑在地铁隧道施工过程中的施工及运营安全。同时对相关地层的沉降规律的研究也为城市地铁设计施工提供参考依据。
Subway engineering in the city will be the future development trend. Shallow buried tunnel construction in the soil layer with existing buildings is the key of the quality of the subway tunnel. The study on the quality control and deformation law of subway construction under the existing building has important practical science value. The tunnel of Xi＇an subway line 2 which through the pedestrian bridge in Xiaozhai district as an example in the paper, Through effective construction quality control measures ensure the construction process of the subway tunnel construction under the existing building and the operation safety. The study on the sinking law of soil layer provides a reference for the design and constmction of subway.
