摘要: 以昆明地铁某区间盾构隧道为背景,对地铁盾构隧道下穿铁路施工中引起的地表沉降进行了二维及三维的数值模拟,对计算结果结合实际施工进行了相关分析,阐述了盾构过铁路时对周边构筑物的影响及控制措施,以供同类工程参考。

Abstract: This paper presents a case study of the design aspects of a shielded tunnel for the Kunming subway system. The proposed shielded tunnel is crossing the railway train station. The ground settlement induced by this proposed shielded tunnel was simulated by both two and three dimensional numerical approaches. The analytical results are compared with the observed settlement values. This paper also discusses the impact of the shielded tunnel construction on the adjacent structures and measures minimizing the adverse effects.

Key words: shielded tunnel, underpass, railway tracks, ground settlements
