摘要： 邻近地铁区间隧道的基坑开挖施工，毫无疑问会使得隧道产生一定的变形，从而对地铁运营和结构安全产生一定的影响。以南昌轨道交通1号线区间隧道邻近基坑工程为例，详细阐述了基坑开挖过程中采取的各项技术措施，并对数值模拟与监测数据进行了分析对比，为其他同类型工程提供一些参考。

Abstract: The regional metro tunnel is expected to have deflections as results of the nearby deep excavation activities and therefore induce an adverse effect to the safe operation of the metro cars. This paper presents a case history of the excavation near Nanchang Rail Transportation No 1 Line. The measures that were used in the construction to reduce deflection in the operational tunnel are discussed. The construction monitoring results are compared with the numerical results.
