摘要
地表沉降是盾构隧道主要监测方法之一,通过地表沉降规律来指导盾构现场施工。论文以天津地铁5号线"围堤道站～文化中心站"区间、6号线"文化中心站～阳光乐园站"区间和Z1线"文化中心站～尖山路站"区间的三线叠落段为依托,从三线叠落段各线穿越期间的地表沉降变化规律进行分析,并结合盾构的实际施工土压力进行了相关性分析,研究结论可以为以后类似的盾构施工提供一定的参考。
Surface subsidence is one of the main monitoring methods of shield tunnels.The law of surface subsidence is used to guide the construction of shield tunnels.In this paper,taking the three-line overlapping section of Tianjin Metro Line 5 "Weidi Road Station to Cultural Center Station"section,Line 6"Cultural Center Station to Sunshine Paradise Station"section and Z1 line"Cultural Center Station to Jianshan Road Station"section as a basis,paper analyzes the surface subsidence rule during the period of three-line crossing the overlapping section,carries out the correlation analysis of the actual earth pressure in shield tunneling construction.The research conclusion can provide a certain reference for similar shield tunneling construction in the future.
