【摘要】 地铁隧道的开挖对既有城市暗渠及管线的影响是城市地铁建设的重点,文章通过隧道支护结构、周围土体以及雨水暗渠耦合作用的三维有限元分析模型,对青岛地铁3号线江西路站至宁夏路站区间隧道开挖对雨水暗渠的影响进行了仿真分析,并结合实际监控量测结果对隧道施工提出了相关建议。更多还原

【Abstract】 The influence on the drainage culvert and pipelines caused by metro excavation has been the key points in metro engineering.In this paper,applying the three - dimension FEM analysis model considering the coupling action of tunnel support structure,soil and drainage culvert,the simulation analysis of the construction effect of the tunnels on the drainage culvert is per formed between Jiangxi Road Station and Ningxia Road Station of Qingdao Metro line 2,and,combining with the actual measured data.In the end,some instructive conclusions to the metro construction are drawn.更多还原
